UNIX for Dummies Questions & Answers

Hello forum,

I am new to shellscripting.

My first goal is to write a script that verifies that for each file in one path there is an associated one in another path.

The association is deviated by a distinct 'part' of the filename(s). Therefore I wanted to work with substitution.

Here is what I have so far:

Code:

for i in /my/source/path/*
 do
  var=basename $i
  echo ${var//cutme/""}
 done

I expected to put every filename reduced by the string 'cutme' to stdout. But it will tell me it has not sufficient privileges. I think it tries to rename the actual filename, but I just want to work with a 'copy'.

How can I work with filenames without actually changing it?

regards

Try:

Code:

var=$(basename $i)

or

Code:

var=${i##*/}

It worked.
Thank you Scrutinizer.

So

Code:

var=$(some)

means copy the value to a new variable?

This is called command substitution.
