mkdir & cd into it as single command

The biggest advantage of this over the functions is that it is portable.
This is sample output - yours may be different.

mkdir /home/foo/doc/bar && cd $_

Create a directory and change into it at the same time

How often do you make a directory (or series of directories) and then change into it to do whatever? 99% of the time that is what I do. This BASH function 'md' will make the directory path then immediately change to the new directory. By using the 'mkdir -p' switch, the intermediate directories are created as well if they do not exist. Show Sample Output
This is sample output - yours may be different.
```
abd-pb-2:bin md test
abd-pb-2:test md a/b/c/d/e
abd-pb-2:e 
```

md () { mkdir -p "$@" && cd "$@"; }

Smart `cd`.. cd to the file directory if you try to cd to a file

This little function will smarten 'cd'. If you try to cd into a file (which I guess we all have done), it cd's into the directory of that file instead. I had to use nesten if's, to get cd to still work with 'cd' (to get to $HOME), 'cd -' (to get to last directory), and 'cd foo\ bar'. Show Sample Output
This is sample output - yours may be different.
```
{ /root } # tail /var/log/messages
{ /root } # ... # ohh, I need to watch more logfiles
{ /root } # cd <alt+.> # to get last parameter
{ /var/log } # # Ready for action in the files folder
```

cd() { if [ -z "$1" ]; then command cd; else if [ -f "$1" ]; then command cd $(dirname "$1"); else command cd "$1"; fi; fi; }

Quickly CD Out Of Directories Without 5+ Aliases

I wrote this a long time ago, wondering why this wasn't floating around somewhere out there (at least not where I could find).. this seems much more simple than multiple aliases and can cd out of directories easier. Show Sample Output
This is sample output - yours may be different.
```
Add this to your .BASHRC file and you can simply type up to cd back one directory, up 2 to cd twice, up 10 to cd ten times... better then b,bb,bbb,bbbb aliases
```

up() { local x='';for i in $(seq ${1:-1});do x="$x../"; done;cd $x; }

Get absolut path to your bash-script

Another way of doing it that's a bit clearer. I'm a fan of readable code.

cd to (or operate on) a file across parallel directories

This is useful for quickly jumping around branches in a file system, or operating on a parellel file. This is tested in bash. cd to (substitute in PWD, a for b) where PWD is the bash environmental variable for the "working directory" Show Sample Output
This is sample output - yours may be different.
```
[root@centos manifests]# pwd
/etc/puppet/modules/nfs/manifests
[root@centos manifests]# cd ${PWD/nfs/packages}
[root@centos manifests]# pwd

.. or operate on a file in parallel directory
[root@centos manifests]# vi ${PWD/packages/nfs}/init.pp

cd ${PWD/a/b}

Quickly CD Out Of Directories

`up 3` will climb the directory tree by three steps. `up asdf` will do nothing, and returns exit code 1 as an error should.

move up through directories faster (set in your /etc/profile or .bash_profile)

Usage: up N I did not like two things in the submitted commands and fixed it here: 1) If I do cd - afterwards, I want to go back to the directory I've been before 2) If I call up without argument, I expect to go up one level It is sad, that I need eval (at least in bash), but I think it's safe here. eval is required, because in bash brace expansion happens before variable substitution, see http://rosettacode.org/wiki/Repeat_a_string#Using_printf
This is sample output - yours may be different.

function up { cd $(eval printf '../'%.0s {1..$1}) && pwd; }

Go up multiple levels of directories quickly and easily.

This is a kind of wrapper around the shell builtin cd that allows a person to quickly go up several directories. Instead of typing: cd ../.. A user can type: cd ... Instead of: cd ../../.. Type: cd .... Add another period and it goes up four levels. Adding more periods will take you up more levels.
This is sample output - yours may be different.
5

cd() { if [[ "$1" =~ ^\.\.+$ ]];then local a dir;a=${#1};while [ $a -ne 1 ];do dir=${dir}"../";((a--));done;builtin cd $dir;else builtin cd "$@";fi ;}

eightmillion · 2009-10-29 21:43:51 7
cd up a number of levels

Instead of typing "cd ../../.." you can type ".. 3". For extremely lazy typists, you can add this alias: alias ...=".. 2" ....=".. 3" - so now you can write just .... !!! NB the .. function needs to be "source"d or included in your startup scripts, perhaps .bashrc.
This is sample output - yours may be different.

function ..(){ for ((j=${1:-1},i=0;i<j;i++));do builtin cd ..;done;}

cd into another dir to run a one-liner, but implicitly drop back to your $OLD_PWD after

Obviously the example given is necessarily simple, but this command not only saves time on the command line (saves you using "cd -" or, worse, having to type a fully qualified path if your command cd's more than once), but is vital in scripts, where I've found the behaviour of "cd -" to be a little broken at times. Show Sample Output

Burn a directory of mp3s to an audio cd.

This uses mpg123 to convert the files to wav before burning, but you can use mplayer or mencoder or ffmpeg or lame with the --decode option, or whatever you like.

Open a manpage in the default (graphical) web browser

An easy alias for opening a manpage, nicely HTML formatted, in your set internet browser. If you get a "command exited with status 3" error you need to install groff.

To create files with specific permission:

Dump audio from video without re-encoding.

This removes the video and subsequent file size and directly copies the audio.

Clean all .pyc files from current project. It cleans all the files recursively.

check for write/read permissions

su www-apache/ftp user and then check readable: find ~/ -type d $ -wholename '/dev/*' -o -wholename '/sys/*' -o -wholename '/proc/*' $ -prune -o -exec test -r {} \; -exec echo {} readable \; 2>/dev/null check writable: find ~/ -type d $ -wholename '/dev/*' -o -wholename '/sys/*' -o -wholename '/proc/*' $ -prune -o -exec test -w {} \; -exec echo {} writable \; 2>/dev/null

Which processes are listening on a specific port (e.g. port 80)

swap out "80" for your port of interest. Can use port number or named ports e.g. "http"

tar exclude files or directories

If you want to exclude only one file or directory you should use as --exclude=file_or_directory

Terrorist threat level text

Convert seconds to [DD:][HH:]MM:SS

Converts any number of seconds into days, hours, minutes and seconds. sec2dhms() { declare -i SS="$1" D=$(( SS / 86400 )) H=$(( SS % 86400 / 3600 )) M=$(( SS % 3600 / 60 )) S=$(( SS % 60 )) [ "$D" -gt 0 ] && echo -n "${D}:" [ "$H" -gt 0 ] && printf "%02g:" "$H" printf "%02g:%02g\n" "$M" "$S" }

Pipe any JSON to jq, then count with the appropiate expression and use the | length on the array
