comment Sorting a file based on second column in a Tab Spaced file
Sorry, it won't let me submit without an account. If you want help you are going to have to actually tell us what the problem is.

I typed exactly what you have in to the website and it says it worked for me.

It's better to copy and paste the question text instead of linking to it.

comment How can I run a command in bash after any change in $PWD?
@NathanLong that's only for my operating system. Operating system seems irrelevant here. Does OS matter? It's the shell that matters in your question, and you seem to be specifically asking about bash, which works pretty much the same on all operating systems that it runs on.

@NathanLong "how many other ways are there to change directory" - I don't know - You can find out though, because the number of shell builtins is limited and can be found in the manual.

comment How can I run a command in bash after any change in $PWD?
What tool do you keep referring to? Why not use zsh? The DEBUG trap approach is pretty clunky too because there is only one DEBUG trap so if every add-on script that tries to be clever has the same idea they will clobber each other.

comment Video-inverting my bash prompt
@SopalajodeArrierez A leading zero is part of the conventional syntax for denoting octal notation, and octal is what is required here. 033 is 27 in decimal (3 * 8 + 3), not 33.

Why not redefine cd, pushd, and popd? How many other ways are there to change directory?

comment Why are some processes “killable” by pkill but not killall?
Doesn't your linked question answer yours? killall does exact matching but pkill does not. Is that not the answer?

Update your question. What is this command that runs every 5 seconds supposed to accomplish?

Does fs_usage ever terminate? If not you need a different approach. What tail does is get you the last line(s). It can't know what the last line is until its input terminates, so as long as the pipe chain is held open tail will never output anything.

You should specify what shell you are using.

comment Increasing ulimit stack size benefits?
As far as I know, stack size should not affect speed. If you don't have enough you crash with a stack overflow error. More stack usually should not affect performance.

comment Print last character in the given path
@Aravind Albert's answer assumed you were using bash. If you are using ksh there may be feature differences causing your error. See my answer for something that works in all shells.

comment Rename files with even numbers
@KasiyA I see, the leading zeroes were being interpreted as octal numbers. Stripping out the leading zeroes seemed like the easiest way to fix that issue.

@KasiyA I am not sure what you mean. What file name?

comment find the max value of column 1 and print respective record from column 2 from file
This should work but is inefficient, because sorting is overkill when the task is to find a maximum.
