Unix Tip #4568- September 13, 2013

-------- REMOVE THE DASHES


Have you ever accidentally created a file beginning with '-'?
It happens often by mistake and from the first look it seems
like you can't delete the file (rm thinks the initial - is an
option, and doesn't recognize the file).

The simple, quick way around this is the -- option to rm.
Say you had the file ---hey in the current directory:

$ ls ---hey

/bin/ls: unrecognized option `---hey'
Try `/bin/ls --help' for more information.

$ ls|grep hey
---hey

$ rm ---hey
rm: unrecognized option `---hey'

Try `rm --help' for more information.
$ rm -- ---hey

( ls also has an -- option: )

$ ls -- ---hey
/bin/ls: ---hey: No such file or directory
$
