To delete files with control characters in them like ^M or ^L use the control-V shell feature. This tells many shells to interpret the next input character as a literal character (instead of as a control character).

To delete a file with a space before the ctrl-L “ ^L” you would issue the following keystrokes in this order (separated by commas) r,m, ,\, ,ctrl-v,ctrl-l. The \ escapes the space. The command looks like:

rm \ ^L
