SED - replace line after substing

Hi,

How do I replace the line content after a particular string ?

For example:
If I have the below lines;
ABCD
1234\00
EFGH
5678\00

How do I replace the line after "ABCD" string to be 1111.
ABCD
1111\00
EFGH
5678\00

Please note that I don't know the line content after the string.

Use the n command of sed to go to the next line, then apply the substitution:

Code:

sed '/ABCD/{n; s/.*\(\\00\)/1111\1/} file

This changes every string from the beginning of the line after ABCD to "\00" (which is preserved).
