  • List latest 5 modified files recursively

    This command will find any named file types in / between two dates then will list all the metadata of those files in long format and human readable form. Adding a 't' flag to the ls command sorts the files by modified time. After all that the head -5 lists the first 5 which can be changed.

  • See how many times you've typed 'ls' by itself

    I seem to do this compulsively every time I change directories, sometimes even when I don't, even if I know exactly what I need to do. (Don't worry, the sample output is just an exaggeration. :) Show Sample Output

  • List just the executable files (or directories) in current directory

    ls -l outputs long listing of files to awk, which sorts the output to include all lines that have the executable bit set (-x.), but excludes (!) the lines that have the directory bit set (drw), then prints the results to the screen. Show Sample Output

  • Get the total length of all video / audio in the current dir (and below) in H:m:s

    All the other example fail when running in a folder containing too many files due to * being saturated. This command does not use *, allowing me to run it in one folder containing over 300000 audio files. As to running on so many files, I used GNU parallel in order to spawn as many processes as cores, tremendously fasting up the process. Show Sample Output


    0
    ls|grep ".wav"|parallel -j$(nproc) soxi -D {}|awk '{SUM += $1} END { printf "%d:%d:%d\n",SUM/3600,SUM%3600/60,SUM%60}'

  • Find Duplicate Files (based on size, name, and md5sum)

    It works extremely fast, because it calculates md5sum only on the files that have the same size and name. But there is nothing for free - it won't find duplicates with the different names. Show Sample Output

    find -type f -printf '%20s\t%100f\t%p\n' | sort -n | uniq -Dw121 | awk -F'\t' '{print $3}' | xargs -d '\n' md5sum | uniq -Dw32 | cut -b 35- | xargs -d '\n' ls -lU

  • 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.

Find usb device in realtime
Using this command you can track a moment when usb device was attached.

Redirect STDIN
Several times, I find myself hitting my up arrow, and changing the search term. Unfortunately, I find myself wasting too much time typing: $ grep kernel /var/log/messages Redirecting STDIN allows me to put the search term at the end so I less cursor movement to change what I'm searching for: $ < /var/log/messages grep kernel If you're using the emacs keyboard binding, then after you press your up arrow, press CTRL+w to erase the word. If this has already been submitted, I couldn't find it with the search utility.

Generate Random Passwords
If you want a password length longer than 6, changing the -c6 to read -c8 will give you 8 random characters instead of 6. To end up with a line-feed, use this with echo: # echo `< /dev/urandom tr -dc _A-Z-a-z-0-9 | head -c6` Modern systems need higher strenght, so add some special characters: # < /dev/urandom tr -dc '12345!@#$%qwertQWERTasdfgASDFGzxcvbZXCVB' | head -c8

Calculate pi with specific scale
a() function in bc is for arctangent, available if using -l option included.

Reset hosed terminal,
stty sane resets the tty to basic usable function. The ^J is a newline -- sometimes CR/LF interpretation is broken so use the ^J explicitly.
