有效地将项添加到git索引

Question

I find it very tedious to write full paths when adding changed files to index. For example, i've changed 3 files, but want to commit only 2 of them:

# Changed but not updated:
#   (use "git add <file>..." to update what will be committed)
#   (use "git checkout -- <file>..." to discard changes in working directory)
#
#   modified:   apps/frontend/config/modules/file1
#   modified:   apps/frontend/config/modules/file2
#   modified:   apps/frontend/config/modules/file3

So I have to type as much as:

git add app/frontend/modules/file1 app/frontend/modules/file3

I am looking for a way to add items by their index in the git status list? Something like

git add %1 %3

Answer 1

Use interactive add:

git add -i

It'll ask you for each file, if you want to add it to the commit.

You can even go ahead and pick based on patches, which is always useful:

git add -p

Answer 2

cd apps/frontend/config/modules
git add file1 file3
cd - #go back

Answer 3

您还可以使用shell扩展：

git add app/frontend/modules/file{1,3}

Answer 4

I've been using a similar script I wrote to add only 1 file, eg git nadd N to add the N'th modified file. It shouldn't be hard to modify it to allow several files.

#!/bin/bash

if [[ $# != 1 ]] ; then
    echo "usage: git nadd <index>"
    exit 0
fi

num=$1

# get unstaged modified files
modified_files=$(git status --porcelain | grep " M " | cut -c 4-)

if [[ $modified_files == "" ]] ; then
    echo "error: there are no modified files"
    exit 1
fi

# count how many we have
num_modified_files=$(echo "$modified_files" | wc -l)

if [[ $num -gt $num_modified_files ]] ; then
    echo "error: index larger than number of modified files"
    exit 2
fi

# pick n'th modified file
file=$(echo "$modified_files" | sed -n "$num p")

# fix $file to full path in case we're not in root
root=$(git rev-parse --show-cdup)
file=$root$file

git add -- "$file"
