Add Rudimentary Logging Levels According to STDOUT/STDERR

This is a bit of a bash hack to catch STDERR and append a log level to it. So for example, if your script has pseudo loglevels like so: echo "INFO - finding files" [ -f ${files} ] || echo "WARN - no files found" Any subcommands that write to STDERR will screw that up Adding 2> >(fb=$(dd bs=1 count=1 2>/dev/null | od -t o1 -A n); [ "$fb" ] && err=$(printf "\\${fb# }"; cat) && echo "ERROR - $err") to the command does the following: 2> Redirect STDERR >( Spawn a subshell (STDERR is then redirected to the file descriptor for this subshell) fb=$(....) get the first byte of input [ "$fb" ] test if there's a first byte && err=$(printf....) save the output to the $err variable && echo "ERROR - $err" append your pseudo loglevel and the error message Heavily borrowed from https://unix.stackexchange.com/questions/33049/check-if-pipe-is-empty-and-run-a-command-on-the-data-if-it-isnt Show Sample Output

Scrollable Colorized Long Listing - Hidden Files Sorted Last

To sort hidden files first, simply switch the two inner `ls` commands. I have this aliased to `dira` `dir` is aliased to the simpler version with no hidden files: $ ls -l --color=always | less -R

list files recursively by size

Remove a range of lines from a file

Setup an ssh tunnel

Uses ssh as tunnel tunnel for an other connection. -f runs ssh in the background -N tell that there is no command to run -L deals with the forwarding aspect where the first number is the local port number, the second is parameter is the name of the server to forward to and the third parameter is the port number on that server. The last part of the command is the usual ssh form consisting of the user name and remote server name

Rename files in batch

Create full backups of individual folders using find and tar-gzip

Problem: I wanted to backup user data individually. In this example, all user data is located in "/mnt/storage/profiles", and about 25 folders inside, each with a username ( /mnt/storage/profiles/mike; /mnt/storage/profiles/lucy ...) I need each individual folder backed up, not the whole "/mnt/storage/profiles". So, using find while excluding directories depth and creating two variables (tarfile=username & desdir=destination), tar will create a .tgz file for each folder, resulting in a "mike_full.tgz" and "lucy_full.tgz".

Bruteforce dm-crypt using shell expansion

Lost your luks passphrase? You can always bruteforce from the command line. See the sample output, a simple command for the "pass" word, using combinations of upper/lowercase or number replacement. The generated combinations are: for a in {p,P}{a,A,4}{s,S,5}{s,S,5}; do echo $a; done pass pasS pas5 paSs paSS paS5 ...

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"
