Add default flags for programs used with exec

[cohml]

Very very often I use fd to grep inside many files at once. For example:

fd . -e py -X grep foo

However, the results come back without color, which can be hard to parse. So I must always manually specify --color=always:

fd . -e py -X grep --color=always foo

This left me wondering if it were somehow possible to, without relying on global aliases, configure things such that when I pass command X into exec/exec-batch, default flags appropriate for X would also be automatically supplied.

For example, perhaps some fdexec.rc/fdx.rc file with contents like

du="-h"
grep="--color=always --line-number"
rm="-i"

Let me know you think about this proposal, or if the desired behavior is already possible, please let me know how. Thanks!

A possible work around for this:

Create a wrapper script that looks like

com="$1"
shift

case "$com" in 
  du) du -h "$@";;
  grep) grep --color=always --line-number "$@";;
  rm) rm -i "$@"
esac

then you can use fd . -e py -X invoke grep foo

where invoke is the name of your script.

Hey that's pretty slick, thanks @tmccombs!

Not as simple or elegant IMHO as supporting this feature natively from within fd as I initially described. But in the meantime, your proposal is a very nice stopgap solution.
