comment Is getline in awk command safe to use?
I don't think there is anything wrong with awk's getline function per se. It can be a code smell though as it is easily misused, either (a) in un-idiomatic constructions when awk already supports line-by-line pattern-action operation, or (b) in attempting tasks too complicated for awk. I would liken it to the much debated goto statement in C in these respects: potentially useful, easily abused.

comment Make firefox command run downloaded firefox instead of iceweasel
This /usr/bin/firefox script is provided by Debian so that users who try to use firefox get something functionally equivalent instead of a "command not found" error. Since it is provided by Debian, it is generally advised to not edit the file, as there are cleaner and easier ways to go about it. The answer depends on how did you install firefox and where did you install it to?

comment Recursively iterate through files in a directory
find ... -exec bash -c 'echo filename is in \$0: "$0"' {} \; is a better way to do it.

comment Extract file name from find command
Forget the find part for now. Do you even have the mailing part working correctly? First come up with a mail_file.sh script or one liner that does what you want, and then use it in find. find itself is not a scripting language. You can't just chain -exec like that.

comment How to combine Bash's read with HERE-document when shopt -os errexit is in place?
@mikeserv Did you confuse me with OP? I am not the one that asked the question. Ask OP, not me. Note that your question is something I already pointed out to the OP in my first comment: "I assume your actual code is a bit more complex than your toy example, because in this case assigning to the variable directly would be much simpler.", i.e. desc='bla bla'.

comment Make vim stop splitting my Git commit messages
(continued)... So, this is not technically an answer, but you are supposed to make the highlighting not ugly by writing a properly formatted git commit message. Try to keep line one below 50 characters. Line 2 is supposed to be blank, which is why it is being colored a BOLD RED for "Warning: this text isn't supposed to be here!" Type the extended message beginning on line 3. Vim will automatically break your lines at 72 characters. Let it do so. If you need Vim to redo the line breaks because you did some editing, highlight the paragraph and do gq to fix the line breaks.

comment Make vim stop splitting my Git commit messages
This is Vim's built-in file type syntax highlighting for git commit messages trying to enforce a certain format for git messages. Your highlighting looks ugly because your git commit message is "ugly", in the sense that it does match the format Vim is expecting you to follow. Both the gitcommit.vim syntax highlighting module and the guidelines were written by Tim Pope. You can read them here: tbaggery.com/2008/04/19/a-note-about-git-commit-messages.html. For a quick summary, make the first line a 50 character summary, leave a blank line, and then write your paragraphs below.

comment How to combine Bash's read with HERE-document when shopt -os errexit is in place?
See unix.stackexchange.com/q/13272/9537. What you want is read ... <<EOF || true not read ... || true <<EOF. The <<EOF is for the read not the true. I assume your actual code is a bit more complex than your toy example, because in this case assigning to the variable directly would be much simpler.

comment sudoers conditional/combo command is possible?
@AquariusPower "only-writeable by root" is not the same thing as "owned by root" and it is the former that matters.

It should be the first, commas with no spaces. Can you post the exact line you are having trouble with?

comment Use find to find certain directory and delete all files in it except one directory
What happens if you have a directory like ./Library/Caches/not_Snapshots/Caches/Snapshots/? Do you want to delete that directory because it is inside ./Library/Caches/not_Snapshots/ or save it because it is a Snapshots directory?

comment Looping the listing files in UNIX
The problem is you haven't explained what you want to do. "Check" is not an executable that you run. "Check" is something you can do with your eyes by looking to see if there is a d. Also, I presume your choice of -rt means the sort order is significant?

comment Looping the listing files in UNIX
You can already see which are directories - those are the ones that start with d.

comment Why does vim color this .bashrc line incorrectly? Fixable?
What Vim version do you have? I tried pasting that sqlplus line into my bashrc and Vim 7.3 highlights it correctly. What is your filetype set to? (:set ft? or :echo &ft). Since the highlighting in your image is wrong but the bash syntax is correct, either you have the wrong filetype or the syntax file you have in your Vim is bugged.

comment Guard against killing an already killed process
@JosephR. The right solution to that (completely different problem) is something along the lines of kill pid || true. When all you have is a PID, it is impossible to avoid race conditions if the state of the PID changes between when you check it and when you try to do something with it.

comment Guard against killing an already killed process
If the PID does not exist because the process has already completed, the kill command will be completely harmless. Why do you even need to check this?

comment sed's c command outputs current line no matter what
This behavior for the c command is also specified by POSIX: "Delete the pattern space. With a 0 or 1 address or at the end of a 2-address range, place text on the output and start the next cycle."
