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.

Mount and umount iso files

Add the functions to the .bashrc to make it work Example: First go to the iso file directory and type: ---------------------------------------------------------------------------------------------------- user@box:~$ miso file.iso ---------------------------------------------------------------------------------------------------- It will put you into a temporary mounting point directory (ISO_CD) and will show the files You can umount the iso file whatever the directory you are ---------------------------------------------------------------------------------------------------- user@box:~/ISO_CD$ uiso ---------------------------------------------------------------------------------------------------- It wil umount the iso file and remove the temporary directory in your home

Go to the next sibling directory in alphabetical order

Sometimes you have to browse your way through a lot of sub-directories. This command cd to the next sub-directory in alphabetical order. For example, if you have the directories "lectures/01-intro", "lectures/02-basic", "lectures/03-advanced" and so on, and your PWD is "02-basic", it jumps to "03-advanced".
This is sample output - yours may be different.

combine `mkdir foo && cd foo` into a single function `mcd foo`

I find that I create a directory and then cd into that directory quite often. I found this little function on the internets somewhere and thought I'd share it. Just copy-paste it into you ~/.bash_profile and then `source ~/.bash_profile`. Show Sample Output

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;}

Quick directory bookmarks

Set a bookmark as normal shell variable p=/cumbersome/path/to/project To go there to p This saves one "$" and is faster to type ;-) The variable is still useful as such: vim $p/<TAB> will expand the variable (at least in bash) and show a list of files to edit. If setting the bookmarks is too much typing you could add another function bm() { eval $1=$(pwd); } then bookmark the current directory with bm p

to() { eval dir=\$$1; cd "$dir"; }

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.

Grabs a random image from "~/wallpapers" and sets as the background

don't bother spawning a bc process or counting the number of options, just pick a random one. 'sort -R' sorts randomly, so pick the top one.

Go to the next sibling directory in alphabetical order, version 2

Another version based on linkinpark342's contribution. Sometimes you have to browse your way through a lot of sub-directories. This command cd to the next sub-directory in alphabetical order. For example, if you have the directories "lectures/01-intro", "lectures/02-basic", "lectures/03-advanced" and so on, and your PWD is "02-basic", it jumps to "03-advanced".

diff will usually only take one file from STDIN. This is a method to take the result of two streams and compare with diff. The example I use to compare two iTunes libraries but it is generally applicable.

diff is designed to compare two files. You can also compare directories. In this form, bash uses 'process substitution' in place of a file as an input to diff. Each input to diff can be filtered as you choose. I use find and egrep to select the files to compare.
This is sample output - yours may be different.

What's this?

commandlinefu.com is the place to record those command-line gems that you return to again and again. That way others can gain from your CLI wisdom and you from theirs too. All commands can be commented on, discussed and voted up or down.

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" }

get ip of all running docker containers

pretty self explanitory

List only locally modified files with CVS

xargs for builtin bash commands

Similar to xargs -i, but works with builtin bash commands (rather than running "bash -c ..." through xargs)

do 'foo' until it exits successfully, pausing in between crashes

restart a buggy script when it dies. works great for "git svn fetch", which leaks memory like a sieve and eventually dies...making you restart it.

Convert CSV to JSON

Replace 'csv_file.csv' with your filename.

Backup file, create dir and set perms in one shot

Prior to working on/modifying a file, use the 'install -m' command which can both copy files, create directories, and set their permissions at the same time. Useful when you are working in the public_html folder and need to keep the cp'd file hidden.

check open ports without netstat or lsof

Print every Nth line

Sometimes commands give you too much feedback. Perhaps 1/100th might be enough. If so, every() is for you. $ my_verbose_command | every 100 will print every 100th line of output. Specifically, it will print lines 100, 200, 300, etc If you use a negative argument it will print the *first* of a block, $ my_verbose_command | every -100 It will print lines 1, 101, 201, 301, etc The function wraps up this useful sed snippet: $ ... | sed -n '0~100p' don't print anything by default $ sed -n starting at line 0, then every hundred lines ( ~100 ) print. $ '0~100p' There's also some bash magic to test if the number is negative: we want character 0, length 1, of variable N. $ ${N:0:1} If it *is* negative, strip off the first character ${N:1} is character 1 onwards (second actual character).

Run bash on top of a vi session (saved or not saved), run multiple commands, instead of one at a time with :!(bashcommand), type exit and [enter] to get back to where you left off in vi.

Helps when I'm editing a script and want to double check some commands without having to exit out of vi multiple times or having to use another terminal session.
