Question

If I had a collection of executable scripts stored in /opt/bin and wanted to ensure that I could always run them by typing their names only (without typing their paths) what steps would I need to perform? Assume that the bash shell is being used. Write this answer as a list of instructions, as if you were telling a new user exactly what to do

ANSWER:

Yes, if you rename it to script, set the executable bit, use the correct shebang line, and put the folder it is located it, into your $PATH:

mv script.sh script
chmod u+x script
make sure the first line in the script is #!/bin/bash (or the correct interpreter if it's not bash)
PATH=${PATH}:/path/to/script
After that, you can run it just by typing "script arg1".

$PATH is a list of folders, seperated by a :, that the shell looks in, when you execute something without specifying a path. You will need to put that line (the last line) into your .bashrc, (or the file that your shell reads at login, if you are not using bash) to make it permanent.
