# III. Bash

`following are bash specific`



**Explorer Windows File System** (so helpful connecting sub-system partition to main OS)

`open windows file explorer GUI for WSL`

```sh

explorer.exe .

```

##### How to `echo` or `cat` write to a file with Bash:

```bash

cat >> /path/to/existingFile.text<< EOF

some text line 1

some text line 2

some text line 3

EOF

```

switch `cat >>` to `cat >` to create a file instead of append

```bash

cat > /path/to/newFile.text<< EOF

some text line 1

some text line 2

some text line 3

EOF

```



`(( expression ))` <-- this will execute/perform an expression



`print BASH env`

```sh

printenv

```



`echo variables` (example how to access vars in BASH)

```sh

echo $LANG # <-- LANG env var (bash)

```



`$RANDOM in BASH will create a random number`

```sh

echo $RANDOM # <-- 22024 : between 0 and 32767

```



```sh

I=0 # <-- passing this in the terminal will persist a var

(( I++ )) # <-- I will now become 1 and persist

# we don't need to prepend $ for vars in (( expression ))

```



`this will print expressions for (( expression )) operations`

```sh

help let

```

##### `View file "long" with permissions list`

```sh

ls -l

```



`-rw-r--r--` in front of the file indicates the permissions: **`r` = read, `w` = write, `x` = execute**

**output:** `-rwxr-xr-x` <-- see **`x`** by 3 different "users" (all users can execute now)

##### `Give executable permissions to a file`

```sh

chmod +x filename.whatever

```



`man` command is "manual" (like `help`)

```sh

man bash # <-- prints manual for bash

man sleep # <-- prints manual for sleep (binary)

```



**`-e` flag needed for special characters**

```sh

echo -e "\n~~ Countdown Timer ~~\n"

```



`lists root of the file system`

```sh

ls /

```

_ls /bin will list all binaries on the file system. Bash lives here: #!/bin/bash which will use bash commands. we can access other binaries or libraries here_



`lists bash commands`

```sh

help

```



`things we can pass to the bash TEST command (for testing true/false (for ifs or [[ EXPRESSIONS ]]))`

```sh

help test

```



```sh

( expression ) # <-- evaluates expression/returns value

```



```sh

help [[ expression ]] # <-- output below

```



      ( EXPRESSION )    Returns the value of EXPRESSION

      ! EXPRESSION              True if EXPRESSION is false; else false

      EXPR1 && EXPR2    True if both EXPR1 and EXPR2 are true; else false

      EXPR1 || EXPR2    True if either EXPR1 or EXPR2 is true; else false



    When the `==' and `!=' operators are used, the string to the right of

    the operator is used as a pattern and pattern matching is performed.

    When the `=~' operator is used, the string to the right of the operator

    is matched as a regular expression.



    The && and || operators do not evaluate EXPR2 if EXPR1 is sufficient to

    determine the expression's value.



    Exit Status:

    Returns success if EXPR evaluates to true; fails if EXPR evaluates to

    false or an invalid argument is given.



**`we can evaluate any expression in the BASH terminal or .sh script:`**

```sh

[[ 4 -le 5 ]] # <-- `-le` === less-than-or-equal

```



`echo $?`

```sh

echo $? # <-- prints last bash command's EXIT STATUS

0 # <-- 0 === true (0 === no errors)



[[ 4 -ge 5 ]]

echo $?

1 # <-- 1 === false (> 0 === contains errors | "false")

```



```sh

[[ 4 -ge 5 ]]; echo $? # <-- run multiple comands on single line with `;`

1 # <-- output

```



**_we can think of `0` return as TRUE but it actually means `command had 0 errors`_** (***EXIT STATUS***)



`check if a file exists (and output EXIT STATUS)` **`-a | -e`**

_THIS WILL CHECK THE FOLDER FROM WHERE THE COMMAND WAS ENTERED_

```sh

[[ -a countdown.sh  ]]; echo $?

0 # <-- output 0 if file exists

```



`to list all variables in BASH`

```sh

declare -p

```



`all variables: @ | *`

```sh

ARR=("a" "b" "c")

echo ${ARR[@]}



declare -p ARR

# --> declare -a ARR=([0]="a" [1]="b" [2]="c")

# --> -a === array

```



`Read (capture user INPUT)`



`capture user input`

```sh

read

```



`Return IP address of Windows Machine as seen from WSL VM`

```sh

ip route show | grep -i default | awk '{ print $3}'

```

# XIII. Cron

**For Ubuntu/Debian, you can find `cron`logs at:**

```bash

/var/log/syslog

```



# XIV. Postman



`variables created/stored in "Environments" in postman can be passed into fields using {{}}`

```sh

Client ID: {{google_client_id}}

Client Secret: {{google_client_secret}}

```



```bash

grep nri // <--

```



`To get a list of all listening TCP ports using lsof`

```bash

sudo lsof -nP -iTCP -sTCP:LISTEN

```



`using ss tool (formerly netstat) to list all open ports`

```bash

ss -tulpn

```



#  XV. Tree



`tree [OPTIONS] [directory]` ("`.`" might not be necessary)

`List folder structure only directories from current directory`

```sh

tree -d .

```



`List folder structure only directors at depth 1`

```sh

tree -d -L 1 .

```



`List folder structure and all hidden files`

```sh

tree -a .

```



# XVI. Git

`stash only staged files`

```bash

git stash push --staged -m "Stash only staged changes"

```



`tagging commits, usually for release`

```bash

git tag -l # the -l (list) flag is opt

# lists all current tags

git tag v1.0.0 2261e84e

# tags a commit by sha

git tag v1.0.1

# tags your current commit

git tag -a v1.0.2 -m "annotate this tag"

# -a flag for annotate -m for message



git show v1.0.0

# this will show associated commit



git log --pretty=oneline

# shows all commits pretty



git push origin --tags

# this will push all tags that aren't already on the remote up

```



`see all your commits on target branch`

`this is good for branches which constantly merge others in`

```bash

git log your-branch --since="YYYY-MM-DD" --until="YYYY-MM-DD" --author="YourGit.AuthorName"

-- you can find your git author name by running git log

```



`using the git stash stack`

```sh

git stash # puts all workind dir changes on top of stash stack

git stash apply # brings back that level of the stack into working dir (un staged)

git stash pop # same as apply except "pops" that level off the stack (dropping it)

git stash drop # removes the top level of the stack

git stash list # shows the entire stack, the newest is always the lowest number



git stash -u # same as git stash --include-untracked

# will include more than just modified and staged

git stash --all # similar to -u ?



git stash --patch # stash hunk at a time

```



`git status`

```sh

git status -s # short output

```



`if you have changes on your remote that you didn't mean to track:`

`add dir and/or files to .gitignore`

`then use this command to remove from the index (the actual location in /.git/index which is your staging area)`

```bash

git rm --cached put/here/your/file.ext # for files

git rm --cached folder/\* # for directory of files

# append --dry-run # to see what will happen w/o executing

git push ... # to update removal and untrack to remote

```

`CAUTION: i have only used this on auto-generated files, so i safely know they will be recreated locally upon deletion...`

`proceed with caution by backing up files if this is not the case for you...`



`bring committed changes back to working directory (e.g. for committed files you want to stash that have not been pushed`

```bash

git reset HEAD~1 --soft

```



`probably best reset option. discard 2 of 3 git areas`

```bash

git reset --mixed

# discards commit and staged changes (in the git index) but KEEPS changes in your working dir (files in IDE)

```



`show remote repo branches state compared with local branches`

```bash

# git remote show 

git remote show origin

```



`git add --patch "hunks"`

```bash

git add -p # shows hunks diff in CLI

```



`tool for giff from all commits on current branch`

```shell

gitk --all

```



`switch to FILE and discard changes (destructive)`

```bash

git restore

```



`move between branches (replaces checkout) doesn't discard changes`

```bash

git switch # only takes branch as arg

# checkout is for switching tags and commits

```

#### Rebase

`how to proceed in interactive rebase`

```bash

# git rebase -i or something

# once you decide the strategy for rebasing (specific files squash, pick, reword, etc)

# then how to continue after handling merge conflicts and whatnot

git add README.txt && git rebase --continue

```

#### Read git files

`cat-file will decode git object blobs, binaries`

```sh

git cat-file < -e | -p > hash

# -e will emit zero status if object exists and non-zero if object is invalid

# -p will print decoded contents in pretty human readable format



git cat-file -t hash # prints the git object type

# e.g. "tree" or "commit"



git cat-file -s hash # prints the size of the git object

# e.g. 34

```



`how to get git objects to read`

```sh

git log --oneline

# d4d8373 (HEAD -> main, origin/main) commit msg

git cat-file -p d4d8373

# tree 75e196aa96922bb8077c3d3b92621696c109e76f

# author Colin Williams  1743921108 -0500

# committer Colin Williams  1743921108 -0500



# commit msg

git cat-file -p 75e196aa96922bb8077c3d3b92621696c109e76f

# 040000 tree a232127dbaf14b5532426c58551c092e9a1d347b    .github

# the hash i passed as the arg is the tree hash

# .github is the dir i made in this commit

# we can trace the a23212.. commit, and keep getting tree hashes until we get a "blob" hash which is the changed file

# cat-file that hash and we see the literal file contents at the time of the commit

# *bonus* no filename, path or metadata will exist in the blob, that data only exists in the tree object

# (that data is inferred by the location of the object which derrives its hash via SHA-1)



```

`check out parent commit only for specific file`

```sh

git checkout ^ -- 

# stages the "revision" diff

# basically like staging a cherry picked "revert"

# which you can test then decide to stage the revision (like an "undo")

# or toss away the staged revision, resuming current functionality

```



`get merge commits that had conflicts by date`

```sh

git log --merges --since="2024-06-01" --grep="^# Conflicts:" --pretty=oneline

```
