Questions tagged [scripts]
A script is a program or sequence of instructions written in a plain text file. The script interpreter (for example Bash, Python, Perl etc.) reads the file and carries out the instructions as if they had been entered at the command prompt. Use this tag for all questions related to creating, troubleshooting and running scripts.
