AIX 5.3: need help removing zeroes using sed or any other method 1

[dstxaix]

Hi

I have a @ delimited file containing lines like

@00{@00{@00000{@
@0{@000{@

I would like to strip off the zeroes if they are the only values between two @ symbols or if the 2 delimiters have a few zeroes and a "{" character.

I tried below code and it seems to do this only for alernate elements.

sed 's/@[0]*{@/@{@/g' inputfile.txt

Any help is appreciated

The reason it behaves like that is because it only processes each line once. The first part matches the red component, @00{@00{@00000{@, performs the replacement, @{@00{@00000{@, and then starts working on the rest of the string, @{@00{@00000{@. However the blue part no longer matches your search string, so it is not replaced, and the purple part is the next match that sed finds and replaces.

One simple workaround is to to the replacement twice:

sed 's/@00*{@/@{@/g;s/@00*{@/@{@/g' inputfile.txt

Notice I used 00* to mean one-or-more zeros, otherwise the second replacement would just match the first @{@ and do nothing.

This is perfect.

It works for me.
