find -exec with multiple commands

by

I am trying to use find -exec with multiple commands without any success. Does anybody know if commands such as the following are possible?

find *.txt -exec echo "$(tail -1 '{}'),$(ls '{}')" \;

Basically, I am trying to print the last line of each txt file in the current directory and print at the end of the line, a comma followed by the filename.

13 s

find accepts multiple -exec portions to the command. For example:

find . -name "*.txt" -exec echo {} \; -exec grep banana {} \;

Note that in this case the second command will only run if the first one returns successfully, as mentioned by @Caleb. If you want both commands to run regardless of their success or failure, you could use this construct:

find . -name "*.txt" \( -exec echo {} \; -o -exec true \; \) -exec grep banana {} \;
