I was working on a shell script and I accidentally created a file with the variable as its name. Now I have
$file in my
ls output, and cannot remove it. What can I do?
Basically, if you want to do things literal with these weird characters, you need to escape it. In a shell there are several ways to do that. The first one is to prepend a '\' to every character you want to escape. So you can do
rm \$file. Another way is to quote them with single quotes, for example,
rm '$file' or
rm '$'file. Some people also consider double quotes as a mean to "escape", but it only escapes white spaces. For example if you have a file named
a file, you can do
rm a\ file
rm 'a file'
rm "a file"
Some ways to get rid of files with weird names are to use globbing (i.e.,
rm ?file if the first character is something strange, but that would also nuke
Xfile, need to be careful not to match too much, check with
echo beforehand) and/or use the interactive flag:
rm -i *file will ask for all stuff called something
file if you want to delete it.
