[SOLVED] sed substitute everything until character

sqn · 03-30-2010, 09:23 AM

Hi all,

I have the following file:

Code:

1 line
...
49 test test=AA:AA:AA:AA:AA=0

I need to substitute on the line number 49, all text until =.
I have used the following, but with no actual result.
sed -re '49s/^.+\=//' file
and
sed -e '49s/.*[=]//' file

Code:

echo "49 test test=AA:AA:AA:AA:AA=0"  | sed -e 's/^.\+\=//'

sqn · 03-30-2010, 09:32 AM

echo "49 test test=AA:AA:AA:AA:AA=0" | sed -e 's/^.\+\=//'
0

It's no good. the resuls should be: =AA:AA:AA:AA:AA=0

You should tell to match any number of non-"=" characters. This brings to the shortest match (that is the first "=" encountered terminates the matching string).

Code:

sed '49s/[^=]*//' file
