sed does not work properly

[czins]

Hello AIXperts,

I would like to change a pattern in a binary file with the following expression:

cat file | sed "s/c34/s2/" > test

this changes only about half of the occurences of the string c34.

Any ideas ?

Best regards
Stefan

I'd guess you are having multiple instances on a line, and you are only transforming the first one. You need the global clause:

cat file | sed "s/c34/s2/g" > test
