scripts

Random shell scripts for different tasks, written mostly for answers on Stack Overflow:

Examples

Some common command shortcuts for Git et al.:

• auu - apt-get update and upgrade for Debian or Ubuntu
• ga - git add
• gcm - git commit with message quoted automatically
• gpod - git push origin develop (with/without tags)
• gpom - git push origin master (with/without tags)

Some other tools and commands:

• internalip - get your internal IP address
• externalip - get your external IP address
• sound - play a sound a wait to finish
• soundbg - play a sound in background
• sn1/sn2/sn3 - good sounds for notifications
• ok - prints OK/ERROR if the last command succeeded/failed
• oks - like ok but with different sounds played on success/failure

Details

Those commands are mostly for Linux but I would like them to work on as many systems as possible - certainly on all POSIX systems. If anything doesn't work, please post an issue.

Work in progress - more to come. See:

• Installation
• Issues
• Author
• License

Some of those scripts were written for my answers on Stack Exchange:

• Make a sound once process is complete (on Ask Ubuntu)
• How can I get my external IP address in bash? (on Unix & Linux)
• How do I find my internal ip address? (on Ask Ubuntu) Some are just for my own conveniece. Maybe they would be useful to someone else.

Functions

ok-functions

Usage:

sn1
sn2
sn3
ok
oks

For example to hear when a long-running command finishes and to hear a different sound on success and on failure:

Example with success:

ls / && ls /bin && ls /usr; oks

example with error:

ls / && ls /bim && ls /usr; oks

See ok-functions.md for more info.

Installation

Most of those scripts should be stand-alone and can be copied in any place. Those commands describes as functions need to be installed differently, see below.

Installing scripts

My recommendation is to make a ~/bin or ~/scripts directory:

mkdir ~/bin

and put this in your ~/.bashrc or ~/.profile:

[ -d "$HOME/bin" ] && PATH="$HOME/bin:$PATH"

That way it's easy to put any script there:

cd ~/bin
wget https://rawgit.com/rsp/scripts/master/example
less example # see what was downloaded
chmod a+x example

And use it at will. Of course always see what was downloaded first.

Installing functions

Those commands described as functions need to be sourced to work, either manually or in a file like .profile, .bashrc etc.

They don't have to be in your PATH and they don't have to be executable. You can download them whenever you want, for example in your $HOME directory:

cd ~
wget https://rawgit.com/rsp/scripts/master/example-functions
less example-functions # see what was downloaded

Now you source them with . (dot) or source command:

. example-functions

If you put the sourcing line in your .profile or .bashrc they will be available after all logins.

Issues

For any bug reports or feature requests please post an issue on GitHub.
