I'm trying to setup grep
installed with Git Bash for Windows to be available from PowerShell Core.
If I have the following in my Microsoft.PowerShell_profile.ps1
:
Set-alias grep "C:\Program Files\Git\usr\bin\grep.exe"
it works - I can use it with the pipes:
❯ echo abc | grep a
abc
But I'm missing the --color=auto
option that on Linux is usually configured in .bashrc
.
With some research, I found that PowerShell doesn't support aliases with parameters. The workaround is to write a function.
So I did it:
Set-alias _grep "C:\Program Files\Git\usr\bin\grep.exe"
function grep {_grep --color=auto $args}
But it doesn't work. The function configured this way doesn't return any output and freezes the shell.
If I manually provide --color=auto
to grep used in the pipe, it works fine (output is returned and a
is highlighted):
❯ echo abc | _grep --color=auto a
abc
ls --color=auto
used in a function like in the link I provided above also works fine, so I guess that the problem is in my function, which is incompatible with the pipe.
Unfortunately, I don't know PowerShell too well, any ideas?

You need to redirect the piped input to the command you're wrapping.
The most straightforward way is via the $input
automatic variable:
function grep { $input | _grep --color=auto @args }
