Single quotes inside alias terminal4/17/2024 You'll also need to escape a few things within the alias as a result, and you need to escape any of the field arguments to awk since these will get interpreted as arguments by Bash as well when you're setting the alias. If you don't want to chop off the second part of color names with spaces, don't use awk, try sed (and be forewarned that the file in question has a very odd and inconsistent mix of spaces and tabs. To make this an alias, which is possible, you need to use double quotes around the entire value for the alias. Of course, none of that addresses your question about quotes - but it's kinda' a moot point: quoting is hard when your commands are needlessly complex so don't make your commands needlessly complex. They will not interfere with the expansion of the. Perhaps you intended that to be `grep -v "\s"` or `grep '^\S*$`, but still the first issue remains. Double quotes quote spaces and tabs, single quotes, and most meta-characters such as filename wild cards. Then on top of that \S matches anything that is not a space (I think that's what it's for right, that seems to be the resulting behavior) - which will still match lines with a space so long as there is at least one character that is not a space. If you prefer sticking with single quotes to avoid the additional escaping, you can instead mix and match quotes in the same argument: echo 'single quoted. With alias one can redefine an existing command or name a new one. Is it your intent to remove color names with spaces? If so, the space is already gone when you print (just) the fourth column. While I have just one alias in the file it works properly, however when I try to create a new one the terminal fails to recognize the command line. However, there are some single and double quotes in the original command, so the alias fails to be created (ok, it gets created partially, and I can't use it). Aliases Alias is nothing more than a shortcut to a long command sequence. Also your `grep "\S"` is not doing what you think it's doing.
