在 Git 别名中使用条件？

Question

I want to add a confirmation before my Git aliases, eg:

amend = !echo -n 'Confirm: ' && read 'x' && [ $x == 'y' ] && git add -A && git commit -a --amend

This works directly in the terminal, but when I run it as a Git alias, I get:

echo -n 'Confirm: ' && read 'x' && [ $x == 'y' ] && git add -A && git commit -a --amend: 1: [: y: unexpected operator

How can I make this work?

I am suspecting that git aliases use sh by default. Try replacing the == in your test command by = :

amend = !echo -n 'Confirm: ' && read 'x' && [ $x = 'y' ] && git add -A && git commit -a --amend

The == is defined by bash , but not by POSIX. http://www.gnu.org/software/bash/manual/html_node/Bash-Conditional-Expressions.html
