Export all Stremio movie names

I couldn't find movie library on any of the SQLlite Stremio databases, but on ~/.config/stremio/backgrounds2 the background image filenames corresponds to IMDB URL. So I foreach files and wget HTML title of each movie and save it to a file. This will retrieve all movie names, not just the Library.

Run a bash script in debug mode, show output and save it on a file

recurisvely md5 all files in a tree

Found this little gem here: http://info.michael-simons.eu/2008/10/25/recursively-md5sum-all-files-in-a-directory-tree/

list the top 15 folders by decreasing size in MB

Remove ( color / special / escape / ANSI ) codes, from text, with sed

Remove ( color / special / escape / ANSI ) codes, from text, with sed Credit to the original folks who I've copied this command from. The diff here is: Theirs: [m|K] Theirs is supposed to remove \E[NUMBERS;NUMBERS[m OR K] This statement is incorrect in 2 ways. 1. The letters m and K are two of more than 20+ possible letters that can end these sequences. 2. Inside []'s , OR is already assumed, so they are also looking for sequences ending with | which is not correct. This : [a-zA-Z] This resolves the "OR" issue noted above, and takes care of all sequences, as they all end with a lower or upper cased letter. This ensures 100% of any escape code 'mess' is removed.

tail, with specific pattern colored

Help shell find freshly installed applications (re: PATH)

Immediately after installing things into your PATH (e.g. under /usr/bin), currently open shells cannot find them ("zsh: command not found"). Use rehash to get the shell to rescan available executables.

Make alias pemanent fast

Simple function to permanently add an alias to your profile. Tested on bash and Ksh, bash version above. Here is the ksh version: PERMA () { print "$@" >> ~/.profile; } Sample usage: PERMA alias la='ls -a'

grep binary (hexadecimal) patterns

-P activates the Perl regular expression mode.

rename files according to file with colums of corresponding names

Maybe simpler, but again, don't know how it will work with space in filename.

Get full directory path of a script regardless of where it is run from

Also resolves symlinks, showing the full path of the link target
