I wasted two hours reading the sox documentation and searching on the web for the format of some obscure fscking sound sample, and then finally came up with this. This plays only the first three seconds of your unknown formatted sound file using every one of sox's built-in filetypes. If you don't get an exact match, you may get close.
.
I could not fit every single type in and keep it under 127 characters, so you will have to replace "..." with the full list obtainable by `$ sox --help` (or try `Show sample output`)
.
note: /usr/bin/play should be linked to sox on most systems.
You're running a program that reads LOTS of files and takes a long time.
But it doesn't tell you about its progress.
First, run a command in the background, e.g.
$ find /usr/share/doc -type f -exec cat {} + > output_file.txt
Then run the watch command.
"watch -d" highlights the changes as they happen
In bash: $! is the process id (pid) of the last command run in the background.
You can change this to $(pidof my_command) to watch something in particular.
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".
replaces "\n" with "+"
For this hack you need following function:
$ finit() { count=$#; current=1; for i in "$@" ; do echo $current $count; echo $i; current=$((current + 1)); done; }
and alias:
$ alias fnext='read cur total && echo -n "[$cur/$total] " && read'

for one line per process:
$ ss -p | cat
for established sockets only:
$ ss -p | grep STA
for just process names:
$ ss -p | cut -f2 -sd\"
or
$ ss -p | grep STA | cut -f2 -d\"
