Stored Command

This repo contains a small script for storing previously executed command as files along with all parameters etc.

Dependencies

• shfmt
• wordlist
• fc
• read / readarray

Usage

It is sometimes useful to be store a command in a shell script in order to easily re-run it. Especially if the command is long and takes a bunch of various parameters. For instance if you have a curl command that checks some api endpont:

$ curl -XGET -H 'Authorization: Bearer nunorna" https://example.com/api/endpoint

Now you might look this up in history, but sometimes history gets corrupted. So after running the above we can run stc (store command) which will create a hidden folder in the current directory called .stored_command and if this is the first stored command it will be considered the default one and as such be stored in .stored_command/default.sc.sh (after prompting you to confirm the command).

Once the command is stored it can be invoked again with rsc (run stored command). If run without parameters and with only a default command the .stored_command/default.sc.sh file will be passed to source executing the command in the current shell.

If stc is run once more a new file with a five letter word identifier will be generated for the new command. Subsequent runs of rsc without arguments will then prompt for which command to run. If the a name is provided to rsc e.g. rsc happy the .stored_command/happy.sc.sh file will be passed to source

It is also possible to store a command by passing it to stc eg. stc echo hello whould store echo hello as the contents of a file in .stored_command. One caveat to be aware of is if you use this to store a command that uses e.g. a subshell:

stc echo "Current time is $(date)"

In this case $(date) will be evaluated before it is passed to stc however first executing echo "Current time is $(date)" and then excuting stc without parameters will capture the command form the history and will then include the un-evaluated $(date) part.

Additionally lsc can be used to list the currently stored commands in the current directory.

Installation

Add the following line to e.g. your .bashrc file:

source <stored_command_directory>/stored_command.sh

This wll add the stc, rsc and lsc functions to new shells.
