Bash script to run command on all files in folder fails

Question

I would like to run this command on all .wa files within this folder (ideally with subfolders): ./runtest Basic prog -t abc.wa

The script I wrote returns an error:

for filename in ./examples/*.wa;
do
    ./runtest Basic prog -t "${filename}"
done

When running this with ./testscript I get: Syntax error: word unexpected (expecting "do")

Can the script also add to the console output the name of the current file?

Answer 1

You don't need the semicolon unless the do is on the same line.

Answer 2

This command should make it:

find ./examples -type f -name '*.wa' -exec ./runtest Basic prog -t "{}" \; -print

find is your friend. Have a look at its man page, it is worth reading.

Answer 3

To run in all subfolders, use ** as this:

#!/bin/bash

( shopt -s globstar
for filename in ./examples/**.wa
do
    echo "${filename}"
done
)
