As a fan of the one liner...

find /usr/bin -executable -type f | xargs file | grep ASCII

Using 'xargs' to take the output from the find command - files that are executable and provide them as the parameter for the 'file' command. Then grep for the term ASCII to ignore binaries. Please substitute -executable in find command with what style you prefer (see earlier answers) or what works on your 'NIX OS

I required the above to find files with eval in scripts owned by root, so created the following to help find priv escalation weaknesses where root user runs scripts with unsafe parameters...

echo -n "+ Identifying script files owned by root that execute and have an eval in them..."
find /  -not \( -path /proc -prune \)  -type f -executable -user root -exec grep -l eval {} \; -exec file {} \; | grep ASCII| cut -d ':' -f1 > $outputDir"/root_owned_scripts_with_eval.out" 2>/dev/null &

find /usr/bin -executable -type f -print0 | xargs file | grep ASCII

Using 'xargs' to take the output from the find command (using print0 to ensure filenames with spaces are handled correctly). We now have a list of files that are executable and we provide them, one by one, as the parameter for the 'file' command. Then grep for the term ASCII to ignore binaries.
