can't get non-greedy matching to work in sed

lumix · 05-05-2008, 10:18 AM

I want to do something like:

Code:

echo "/1_one/2_two/3_three.xyz" | sed 's/[/].*$/$$$/'

except that I only want to replace "3_three.xyz" and not the whole string, which the above will do. I've tried:

Code:

sed 's/[/].*?$/$$$/'

and tried moving the "?" into different locations, and every permutation of that and parentheses as well. No luck.

How can I do this (with sed)?

Thanks.

Is that an answer :
echo $(dirname "/1_one/2_two/3_three.xyz")'/$$$'

With sed:-

Code:

echo "/1_one/2_two/3_three.xyz" | sed 's|\(/.*/\).*|\1$$$|'

And another sed-version :}

Code:

echo "/1_one/2_two/3_three.xyz" | sed -r 's|(/.+/)[^/]+$|\1$$$|'
/1_one/2_two/$$$
