Grep for multiple strings, show number of lines after one of the strings (but not the other)
I would like to search a file for multiple strings and for one particular string, show the 5 lines following it as well.
cat file | grep -e 'string1' -e 'string2'
works of course, but I would like to get something like
cat file | grep -e 'string1' -e -A 5 'string2'
How can I make it so that (I'm assuming using the -A 5 option) it shows only the lines containing string1 and only the lines containing string2 and the 5 lines after string2, but not the 5 lines after string1?
EDIT: just got it working with awk:
cat file | awk '/string1/{c=1}/string2/{c=5}{while(c-->0){print;getline}}'
shell-script text-processing grep

You can't do that using one go of grep. You need to use two grep instances :
grep 'string1' file; grep -A 5 'string2' file
If you want to run the second upon success of the first one :
grep 'string1' file && grep -A 5 'string2' file
