# exists
Got tired of doing `xargs -I {} sh -c "[ -e \"{}\" ] && echo \"{}\""` to check if a files exist while trying to script things.
This receives paths from standard input, and prints any that exist; Works for files, directories and links.
### Install
```
git clone https://github.com/purarue/exists
cd exists
make install
```
### Usage
```
Usage: exists [-v] [-h]
Read filepaths from STDIN, prints ones that exist to STDOUT
-h show list of command-line options
-v inverts output, prints filenames that don't exist
```
### Example
```shell
$ ls
exists exists.1 exists.c LICENSE Makefile README.md
$ { ls -1; echo 'non_existent_file' } | exists
exists
exists.1
exists.c
LICENSE
Makefile
README.md
{ ls -1; echo 'non_existent_file' } | exists -v # print files that don't exist
non_existent_file
```
