Print umask as letters (e.g. `rwxr-xr-x`) instead of number (e.g. `0022`)

Install with `npm install unix-permissions`. https://github.com/ehmicky/unix-permissions Unix file permissions can take many shapes: symbolic (`ug+rw`), octal (`660`) or a list of characters (`drw-rw----`). `unix-permissions` enables using any of these (instead of being limited to a single one) with any CLI command.

A faster ls

Sometimes "ls" is just too slow, especially if you're having problems with terminal scroll speed, or if you're a speed freak. In these situations, do an echo * in the current directory to immediately see the directory listing. Do an echo * | tr ' ' '\n' if you want a column. Do an alias ls='echo *' if you want to achieve higher echelons of speed and wonder. Note that echo * is also useful on systems that are so low in memory that "ls" itself is failing - perhaps due to a memory leak that you're trying to debug.

netstat -p recoded (totaly useless..)

Ok so it's rellay useless line and I sorry for that, furthermore that's nothing optimized at all... At the beginning I didn't managed by using netstat -p to print out which process was handling that open port 4444, I realize at the end I was not root and security restrictions applied ;p It's nevertheless a (good ?) way to see how ps(tree) works, as it acts exactly the same way by reading in /proc So for a specific port, this line returns the calling command line of every thread that handle the associated socket

p=$(netstat -nate 2>/dev/null | awk '/LISTEN/ {gsub (/.*:/, "", $4); if ($4 == "4444") {print $8}}'); for i in $(ls /proc/|grep "^[1-9]"); do [[ $(ls -l /proc/$i/fd/|grep socket|sed -e 's|.*\[$.*$\]|\1|'|grep $p) ]] && cat /proc/$i/cmdline && echo; done

Show All Symbolic (Soft) Links

Shows all linked file and destinations. The 'ls -l' command lists the files in long (1 file per line) format, and the grep command displays only those lines that starts with an l (lower case L) -- a linked file. Updated: Remove reference to hard links because this command does not apply to hard link as others kindly pointed out. Show Sample Output

list with full path

Use the -a flag to display all files, including hidden files. If you just want to display regular files, use a -1 (yes, that is the number one). Got this by RTFM and adding some sed magic. [bbbco@bbbco-dt ~]$ ls -a | sed "s#^#${PWD}/#" /home/bbbco/. /home/bbbco/.. /home/bbbco/2011-09-01-00-33-02.073-VirtualBox-2934.log /home/bbbco/2011-09-10-09-49-57.004-VirtualBox-2716.log /home/bbbco/.adobe /home/bbbco/.bash_history /home/bbbco/.bash_logout /home/bbbco/.bash_profile /home/bbbco/.bashrc ...

List only directories, one per line

Normally, if you just want to see directories you'd use brianmuckian's command 'ls -d *\', but I ran into problems trying to use that command in my script because there are often multiple directories per line. If you need to script something with directories and want to guarantee that there is only one entry per line, this is the fastest way i know Show Sample Output

Generate a random password 30 characters long

Switch to the previous branch used in git(1)

Very useful if you keep switching between the same two branches all the time.

Compare two directories

Output of this command is the difference of recursive file lists in two directories (very quick!). To view differences in content of files too, use the command submitted by mariusbutuc (very slow!): $ diff -rq path_to_dir1 path_to_dir2

Google dictionary of word definitions

$ wget -qO - "http://www.google.com/dictionary/json?callback=dict_api.callbacks.id100&q=steering+wheel&sl=en&tl=en&restrict=pr,de&client=te" this does the actual google dictionary query, returns a JSON string encapsulated in some fancy tag $ sed 's/dict_api\.callbacks.id100.//' here we remove the tag beginning $ sed 's/,200,null)//' and here the tag end There are also some special characters which could cause problems with some JSON parsers, so if you get some errors, this is probably the case (sed is your friend). I laso like to trim the "webDefinitions" part, because it (sometimes) contains misleading information. $ sed 's/\,\"webDefinitions.*//' (but remember to append a "}" at the end, because the JSON string will be invalid) The output also contains links to mp3 files with pronounciation. As of now, this is only usable in the English language. If you choose other than English, you will only get webDefinitions (which are crap).

Go (cd) directly into a new temp folder

This command create a new temp directory using mktemp (to avoid collisions) and change the current working directory to the created directory.

Get AWS temporary credentials ready to export based on a MFA virtual appliance

You might want to secure your AWS operations requiring to use a MFA token. But then to use API or tools, you need to pass credentials generated with a MFA token. This commands asks you for the MFA code and retrieves these credentials using AWS Cli. To print the exports, you can use: `awk '{ print "export AWS_ACCESS_KEY_ID=\"" $1 "\"\n" "export AWS_SECRET_ACCESS_KEY=\"" $2 "\"\n" "export AWS_SESSION_TOKEN=\"" $3 "\"" }'` You must adapt the command line to include: * $MFA_IDis ARN of the virtual MFA or serial number of the physical one * TTL for the credentials

Diff on two variables

You got some results in two variables within your shell script and would like to find the differences? Changes in process lists, reworked file contents, ... . No need to write to temporary files. You can use all the diff parameters you'll need. Maybe anything like $ grep "^>" is helpful afterwards.

find an unused unprivileged TCP port

Listing today’s files only

list files recursively by size
