I have the following pattern :
foo bar
with foo being always the same, but bar can change. I have an hash table that, for each value of bar, has a new one. What I do now is:
sed -i 's/foo bar/foo new_value/g' file
I am pretty sure there is a way to avoid repeating the foo in the replacement string. Does sed provide something like this ? Like
sed -i 's/foo @@bar@@/new_value/g' file
@@string@@ being the value that has to be replaced.

sed -i 's/(foo )bar/1new_value/g' file
The ( )sequence "captures" the text which then can be placed in the replacement string as 1. This can be done multiple times, the digit in 1 indicates which captured text to use. Captured text is counted in order of ( order.
