I want to post-process the output of an ‘ls’ command with ‘sed’ so that I can remove the ‘./’ prefixes that I can’t avoid going into the ls output (this is a result of using ‘find’ safely).
The thing is, if I pipe ls output to sed, then the default –color=auto setting applies and ls detects that it’s not talking to a terminal so doesn’t output colour codes. But I want colour codes, usually, so I need to change the ls command to use –colour=always, which I’ve done. This means I can have colour and also have sed format the ls output.
The problem is then what happens if I want to pipe my output to ‘less’? Then the colour code commands appear as garbage in the output stream. So, usually I want colour codes, and sometimes I don’t.
