ShellFunctions

Developing few shell functions that ease up my daily linux experience. Add these to ~/.bashrc and execute bashrc to use them ( . ~/.bashrc)

1. Android repo sync
Usage - syncc
function syncc()
{
time repo sync --force-broken --force-sync --no-clone-bundle --quiet --current-branch "$@"
}

2. Youtube to mp3 download
Usage - download <youtube url>
function download()
{
youtube-dl -x --audio-format mp3 "$@"
}

3. My favourite .. grep for stuff recursively, ignoring the case and also hidden directories
Usage - mygrep <string>
function mygrep()
{
grep -i -r --exclude-dir=".*" "$@"
}

4. Find a running process
Usage - process <process name>
function process()
{
ps aux | grep "$@"
}
More to come.. making them as need comes up!

8. Aapt dump of apk resources
