# scriptlets
A collection of tiny but helpful shell scripts for personal use.
Tested with current Ubuntu and macOS.
Licensed under [GPL v3](http://www.gnu.org/copyleft/gpl.html).
To install all scripts to `~/bin` (by creating symbolic links), clone the project and type `make`. Or run the [`bootstrap`](bootstrap) script:
```sh
curl -s https://raw.githubusercontent.com/krlmlr/scriptlets/main/bootstrap | sh
```
# Actively used tools
## Notifications
### n
Execute command in the foreground and show desktop notification after completion.
Currently macOS only.
### bkg
Execute command in the background and show desktop notification *in case of error*.
Currently macOS only.
## h and s
Iterate over all worktrees under the current Git repository and execute a command in each of them.
With `h`, the command is executed directly.
The `s` command prepends `git`, it is a wrapper around `h git` .
Supported switches:
- `-i` or `--interactive`: run the command in interactive mode, turn off parallel propcessing (with aliases `hi` and `si`)
- `-p` or `--paged`: show the output of the command in a pager (with aliases `hp` and `sp`)
- `-n` or `--dry-run`: show the command that would be executed, but do not execute it
- `-x` or `--log-commands`: also log the commands that are executed
`gita` both does too much and not enough, let's see how far I can get with home-grown scripts.
`g` is a simple forwarder to `git`.
FIXME: Integrate with `inside` and `every`
## rh
Start RStudio with an `.Rproj` project file found in the current directory.
If no project file is found, it is created using `usethis::use_rstudio()`.
## fsed
Run `gsed` on files in subdirectories.
## git-mmv
Allows you to write `git mmv` to move several Git-controlled files at once, with the usual `mmv` syntax.
## git-merge-into
Merges the current branch into another branch without altering the current working copy.
## pmake
Parallel `make`, uses number of CPU cores as number of jobs.
## retry
Execute command until success, with increasing time intervals between failures.
## cgrep
Colorful `egrep` .
## pdfcat
Concatenate multiple PDF files into a single document.
## git-bubble
How far can the most recent commit be pushed back up in the history without introducing merge conflicts?
FIXME: Add option to run code (check for semantic conflicts).
## soffice-macos
Launch LibreOffice/OpenOffice on macOS with proper environment setup.
## k
A simple forwarder to `kubectl`.
# To be reviewed
## Run commands in subdirectories
### inside
Execute command inside a subdirectory, given as first argument.
### every
Treat each line of the standard input as subdirectory to execute command in (via `inside`).
### each
Like `every`, but in parallel.
### everyfile
Execute command in each subdirectory (via `inside`).
FIXME: Currently assumes that the current directory only has subdirectories, not files.
### eachfile
Like `everyfile`, but in parallel.
## gh-mirror
Mirrors GitHub issues in a subdirectory of `.git` for offline use. A low-tech wrapper for `wget`.
## git-backup
Tracks the files that Git does *not* track in a shadow Git repository.
## git-backup-all
Treat a whole tree of Git repositories with `git-backup`.
## git-merge-update
Simplifies maintenance of "development" branches that contain several feature/bugfix branches.
## git-rsync
Allows repeated Git-less synchronization with remote locations via `rsync`.
## imgdiff and imgdiff-bg
Compare two images side by side and show differences in a middle pane. Requires ImageMagick. The `-bg` script exits immediately. Usage: `git difftool -x imgdiff-bg -y `. ([Source](http://www.akikoskinen.info/image-diffs-with-git))
## machine-load
Connects to remote machines and shows the top 5 processes by CPU consumption.
## ogv-to-gif
Convert a video to an animated GIF.
## slecho
Echoes each of its parameters on a single line.
## rpt
Repeat a command (default: `make`) as soon as the contents of the current working directory change.
## reprex
Reproducible shell examples.
FIXME: This is likely better solved with `script` .
```sh
~ ( echo "echo a"; echo "echo b" ) | reprex
echo a
echo b
# a
# b
```
Step by step:
1. Type `reprex` on the shell.
2. Type `echo a` on the shell.
3. Output:
```sh
echo a
# a
```
4. Type `echo b` on the shell.
5. Output:
```sh
echo b
# b
```
6. Type on the shell.
Not perfect, but a start.
