将zsh函数参数传递给grep -E

Question

Background...

Trying to find which commit(s) last touched a specific file.

I can do this on the CLI piping from git-log to grep but I'm trying to wrap this in a zsh function, more for ease of memory.

Here's my function, and then here is the output I'd like to generate with it.

# match lines from git log that start with commit or include the
# filename I'm interested in and then pipe back through grep to color the output
glpg() {
  \git log --name-only | \grep -E ‘“$"|^commit\s\S' | \grep -B1 --color -E ‘$'
}

Desired usage and output

dwight:assets (add-analytics*) $ glpg clickouts

Answer 1

Three problems.

• You use Unicode apostrophes and quotes, ' and “. Replace them with ASCII quotes and doublequotes.
• You can't use \\s and \\S to mean space or non-space with a standard (POSIX) grep. Use ' ' and [^ ] instead to be portable.
• The list of all args is referenced with "$@" including the double quotes.
