comment replace comma in specific column value
Judging by your sample input you could just delete all commas everywhere with tr -d , < file.txt > output

comment Piping the output of ls or tree to less loses colors?
@Tim 2 reasons: 1. less removes the colors by default unless you give it the -R option, which tells it to leave it in, and 2. tree and ls and other programs usually turn coloring off when they detect their output is going to another program (like less) instead of directly to your terminal, unless you force the coloring on with -C or --color=always.

comment Symbolic link permission changes
I don't think you can change it. The permissions on a symbolic link don't matter, and are always displayed as 777. Only the permissions on the file it points to matters.

comment How do back-references match in sed?
@dpinvidic :1111 and :2222 are very similar. You should be able to easily see that the pattern matches both strings. Your question should not be "why does this pattern match :2222", because that should be obvious (it's almost the same string as :1111), but rather "why does this pattern NOT match :1111 when :1111 comes before :2222". I explained that in my answer. I have edited my answer a bit. Please reread the entire answer carefully.

@Vi. Yes, tail just works on bytes, which means binary files are fine.

comment Change a value in a config file, or add the setting if it doesn't exist?
It is simpler to use if grep -q 'pattern' file instead of if [ $(grep -c ...) -eq 0 ].

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.
