escape any command aliases

e.g. if rm is aliased for 'rm -i', you can escape the alias by prepending a backslash: rm [file] # WILL prompt for confirmation per the alias \rm [file] # will NOT prompt for confirmation per the default behavior of the command

What Others Think

This is particularly useful for 'rm', which many distributions insist on aliasing to 'rm -i' (ignoring the bad habits that this inculcates).

I usually type in the full path to the command to make sure I'm using both the unaliased command and also to make sure I'm not launching something out of /usr/local/bin/. Using full paths to commands is also a good habit for any scripts that may run with elevated privileges.

NOTE: Any type of quoting will work: backslash, single quote, double quote. The Bash Reference Manual says "The first word of each simple command, if unquoted, is checked to see if it has an alias." Thus, these will all execute the real unaliased rm command: \rm file 'r'm file "r"m file 'rm' file "rm" file command rm file The last example doesn't rely on quoting. Moreover, it will execute the rm command even if your defined rm as a function.

Why not use command ... or builtin ... ... to make the selection with Bash? This also circumvents aliases and is safe for use in scripts.

Many distributions insist on 'rm -i' only as a root, and it's done for a good reason
