Question

Answer 1

+4 A:

sed -e 's/^.*\^.*$//' test.file

For example:

$ cat test.file
test.434
test.4343
test.4343t34
test^tests.344
test^34534/test
$ sed -e 's/^.*\^.*$//' test.file
test.434
test.4343
test.4343t34


$

To delete the offending lines entirely, use

$ sed -e '/\^/d' test.file
test.434
test.4343
test.4343t34

Thanks that does work, is there a way to get that to remove the line entirely? Instead of just replacing it with a blank line?

@Chris See update.

Greg Bacon 2010-07-30 18:43:08

Right but, is there a way to do it in one line? More curiosity sake than to negate your solution... :-)_

Chris 2010-07-30 18:43:37

That *is* one line, no?

@Chris The second `sed` command operates on the original `test.file` from your question and does its work in a single step.

Answer 2

A:

other ways

awk

awk '!/\^/' file

bash

while read -r line
do
  case "$line" in
    *"^"* ) continue;;
    *) echo "$line"
  esac
done <"file"

and probably the fastest

grep -v "\^" file

find lines containing "^" and replace entire line with ""
