如何在gitconfig别名中注释bash脚本 [英] How to comment a bash script in a gitconfig alias

问题描述

我在.gitconfig别名中有以下脚本:

I have the following script in a .gitconfig alias:

[alias]
    vx = "!f() { # I want to put a comment here \
                 foo='foo'; \
                 bar='bar'; \
                 separator=': '; \
                 # Comment Here As well \
                 result="${foo}${separator}${bar}"; \
                 echo $result; \
             }; f" 

如果删除评论，效果很好.但是，带有注释的脚本只是无法运行.gitconfig别名中的注释是否使用不同于#的运算符?

If works fine if I remove the comments. However, with the comments the script just fails to run. Do comments inside a gitconfig alias use an operator different from #?

推荐答案

运行 git config alias.vx ，您将看到别名打印为长单行.您不能在行的中间插入shell注释-注释以#开头并在行尾结束.一旦 bash 看到#，它将忽略该行的其余部分.

Run git config alias.vx and you will see the alias is printed as a long single line. You cannot insert a shell comment in the middle of a line — comments start with # and ends at end-of-line. Once bash sees # it ignores the rest of the line.

我能想到的唯一解决方法是插入包含带引号的字符串的虚拟命令.像:Text; (:是shell中的无操作命令;请参阅 echo注释>/dev/null;

The only workaround I can think of is to insert dummy commands that contain quoted strings. Like : Text; (: is a no-op command in shells; see https://linux.die.net/man/1/bash, section "Shell Builtin Commands") or echo Comment >/dev/null;

[alias]
    vx = "!f() { : I want to put a comment here; \
                 foo='foo'; \
                 bar='bar'; \
                 separator=': '; \
                 : Comment Here As well; \
                 result="${foo}${separator}${bar}"; \
                 echo $result; \
             }; f"
