trial-run

Executes a specified command in its dry-run mode, interactively prompts for confirmation, and re-executes it for real.

I got tired of manually executing commands with --dry-run options and then manipulating my shell's command history in potentially error-prone ways to re-execute the command, so I wasted more time writing a script to do it for me. (Yes, I am aware that most POSIX shells would allow me to enter ^--dry-run ^ to perform command substitution, but that's awkward to type and wouldn't work well for interactive scripts.)

Installation

trial-run depends on submodules, so --recurse-submodules is necessary when using git clone:

git clone --recurse-submodules https://github.com/jamesderlin/trial-run.git

Setting git config submodule.recurse true is also recommended so that submodules are automatically and appropriately updated when the parent repository is updated.

Examples

Invoking trial-run rsync -aC --delete SOURCE DESTINATION will execute:

rsync --dry-run -aC --delete SOURCE DESTINATION
rsync -aC --delete SOURCE DESTINATION

Invoking trial-run --command="MAIN_COMMAND --OPTION SUBCOMMAND" -- --SUBOPTION will execute:

MAIN_COMMAND --OPTION SUBCOMMAND --dry-run --SUBOPTION
MAIN_COMMAND --OPTION SUBCOMMAND --SUBOPTION

Invoking trial-run --command="p4 revert" --option=-n will execute:
```
p4 revert -n
p4 revert
```
