hoodedvul

Take into account the main readme for this section. README first.

Description of set -n: Read commands but do not execute them.

Perform syntax check, Intentionally deleted single parenthesis for the functions.

set -n

sys_clean_tmp ) {
printf "\n\033[36m%s\\033[0m\n" "Cleaning temporary files"
cd ~/tmp
rm -f *.core
}

sys_clean_old ) {
printf "\n\033[36m%s\\033[0m\n" "Cleaning temporary files"
cd ~/tmp
rm -f *.old
}

sys_clean_tmp
sys_clean_old

Running the script will produce syntax errors that can be fixed one a time. This is a good way to validate the syntax of your script without running the commands.

$ ./clean
./clean: line 3: syntax error near unexpected token `)'
./clean: line 3: `sys_clean_tmp ) {'

Comment out the set -n line after syntax of script has been checked.
