how to create alias with a command contains ' and "












3














A few posts ago someone asked how to show memory in percentage. someone replied with:
free | awk '/^Mem/ { printf("free: %.2f %n", $4/$2 * 100.0) }'

I was wondering if i can turn this command into an alias in ~/.bashrc. but the syntax of alias is:
alias aliasname='command'

how can I do this? that command contain both ' and ". I tried different ways but I didn't work. is this even possible? am I missing something?

  • To avoid quoting hell it might be easier to just define a function in such cases.

You need:



alias aliasname="free | awk '/^Mem/ { printf("free: %.2f %n", $4/$2 * 100.0) }'"


Notice that you need to escape both " and $.
