Question

我在Stack Overflow上找到了此命令，以计算每个用户对仓库的LOC贡献：

git log --no-merges --pretty=format:%an --numstat | awk '/./ && !author { author = $0; next } author { ins[author] += $1; del[author] += $2 } /^$/ { author = ""; next } END { for (a in ins) { printf "%10d %10d %10d %s\n", ins[a] - del[a], ins[a], del[a], a } }' | sort -rn

但是，当我尝试在.gitconfig中将其作为命令的别名时，会遇到各种错误。我不知道如何正确地转义它，以便当我调用“ git count-lines”时它可以在bash中正常运行。我已经基于StackOverflow上描述git别名的其他问题进行了多次尝试，但是我一直遇到不同的问题。

到目前为止，我已经在gitconfig中尝试了很多东西。这给了我最少的错误：

[alias]
    count-lines = "!f() { git log --no-merges --pretty=format:%an --numstat | awk '/./ && !author { author = $0; next } author { ins[author] += $1; del[author] += $2 } /^$/ { author = \"\"; next } END { for (a in ins) { printf \"%10d %10d %10d %s\n\", ins[a] - del[a], ins[a], del[a], a } }' | sort -rn; }; f"

这是上面给出的错误：

awk: cmd. line:1: /./ && ... printf "%10d %10d %10d %s
awk: cmd. line:1:                   ^ unterminated string  
awk: cmd. line:1: /./ && ... printf "%10d %10d %10d %s 
awk: cmd. line:1:                   ^ syntax error

（据我了解，我在Windows 7计算机上，因此我需要在整个命令周围加上引号）

好吧，经过一个半小时的调试和摆弄，我终于弄清楚了这个问题：我需要在printf语句中的换行符中转义反斜杠。

broken: count-lines = "!f() { git log --no-merges --pretty=format:%an --numstat | awk '/./ && !author { author = $0; next } author { ins[author] += $1; del[author] += $2 } /^$/ { author = \"\"; next } END { for (a in ins) { printf \"%10d %10d %10d %s\n\", ins[a] - del[a], ins[a], del[a], a } }' | sort -rn; }; f"
fixed:  count-lines = "!f() { git log --no-merges --pretty=format:%an --numstat | awk '/./ && !author { author = $0; next } author { ins[author] += $1; del[author] += $2 } /^$/ { author = \"\"; next } END { for (a in ins) { printf \"%10d %10d %10d %s\\n\", ins[a] - del[a], ins[a], del[a], a } }' | sort -rn; }; f"

如何在gitconfig中正确别名此git line-counting命令？
