comment How do you derive a decimal from a math operation involving a variable?
bash only does integer math. Just use awk and be done in one line: awk '{sum += $4} END {print 10^5/sum}' $f

comment Ubuntu installaion doesn't ask for boot loader
What version of Ubuntu and which install method / image did you use? What options did you choose during the install? If the system installed and boots successfully it's not really a problem, is it?

comment Write bash function which operates on list of filenames
I don't think that is proper scp syntax. You can't do user@host:"file list" as far as I am aware. You need to repeat user@host for each file.

comment Run another command before running the command the user wants to run
@IonicăBizău The reason there is no infinite recursion is given in the bash manual: The first word of the replacement text is tested for aliases, but a word that is identical to an alias being expanded is not expanded a second time. This means that one may alias ls to "ls -F", for instance, and Bash does not try to recursively expand the replacement text

comment Increment Numbers in URL?
What are you really trying to do? If you just want to print a list with bash: for i in {192..302}; do echo "http://sample.com/poilus/cwrgshs/$i/$i.html"; done. I smell an XY problem though.

comment In a Bash if condition, how to check whether any files matching a simple wildcard expression exist?
Your answer is different from @ChrisDown's because you parse ls output whereas he does not (he only checks its exit status). Due to the complexities involved with parsing ls output, the fact that ChrisDown avoids it entirely makes his answer more robust and correct than yours, even if yours will work in the many cases where "reasonable" file names (i.e. not containing whitespace) are concerned.

comment Vim colors conflicting with terminal ones
As vim runs in a 256 color terminal it will be limited to the 256 colors the terminal uses, and there is no full RGB terminal I am aware of so @al92's suggestion is unlikely to be possible. The closest you can get is to come up with a scripted command to change terminal colors and arrange to have it run every time you open and close vim to set and reset the terminal colors.
