I need to pass a string to a program as its argument from the Bash CLI, e.g
program "don't do this"
The string may include any character like '$', '\', etc. and I don't want Bash to do any modification. So I think about using single quotes.
However the following does not work:
program 'don\'t do this' //escape doesn't work in single quote
While the following two works:
program $'dont\'t do this' //seems fine, but any other side effects?
program 'dont'\''do this' //breaking into 3 parts
The first approach seems better in that it acquires less pre modification (put the dollar symbol in front and substitute every \ to \\), but I don't know what else the DOLLAR SIGN might do.
I've really googled this but I can't find what I need...
