  • 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.

Extract audio stream from an video file using mencoder
This command extracts the audio stream of the video in $file and stores it in a file where the original suffix is changed to .mp3

Convert a bunch of HTML files from ISO-8859-1 to UTF-8 file encoding in a folder and all sub-folders
This is my first attempt at converting all HTML files to UTF-8 file encoding, including all subfolders. Theres probably a much more compact way to do it, but I'm quite proud of it with my windows background ;)

Ping all hosts on 192.168.1.0/24
Pings all the hosts on 192.168.1.0/24 in parallel, so it is very fast. Alive host IP addresses are echoed to stdout as pings are responded to.

Display the human-readable sizes of all files and folders in the current directory with 3 decimal places
To sort the list by file/directory size, insert `sort -n |` before `awk`.

Realtime lines per second in a log file
Displays the realtime line output rate of a logfile. -l tels pv to count lines -i to refresh every 10 seconds -l option is not in old versions of pv. If the remote system has an old pv version: ssh tail -f /var/log/apache2/access.log | pv -l -i10 -r >/dev/null

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"

display typedefs, structs, unions and functions provided by a header file
will display typedefs, structs, unions and functions declared in 'stdio.h'(checkout _IO_FILE structure). It will be helpful if we want to know what a particular header file will offer to us. Command 'cpp' is GNU's C Preprocessor.

Link a deep tree of files all into on directory
If you want to pull all of the files from a tree that has mixed files and directories containing files, this will link them all into a single directory. Beware of filesystem files-per-directory limits.

Produce a pseudo random password with given length in base 64

Merge several pdf files into a single file
merge a.pdf b.pdf and c.pdf and create ./out.pdf
