Recently, I wrote a script to checkout files from branch because why not. At first I thought of using golang or C#, but bash scripting is the way to go.
In all honestly, this script was made with github copilot, its getting pretty powerful, but this script is also fairly simple.
#!/bin/sh
# this scripts reads files.txt and checks out the files from the repository from the inputted branch
# argument 1: branch name
# argument 2: file.txt
# check if the branch exists
if ! git show-ref --verify --quiet refs/heads/$1
then
echo "Branch does not exist"
exit 1
fi
# check if file exists
if [ ! -f $2 ]
then
echo "File does not exist"
exit 1
fi
# read the file and check out the files
while read line
do
# convert line from windows path to unix path
line=$(echo $line | sed 's/\\/\//g')
echo "git checkout $1 -- $line"
git checkout "$1" -- "$line"
done < $2
Since I use windows + git bash we will need a convert windows file paths to unix, for now I use a simple approach of just parsing backslash.
For example a sample file.txt can be
package.json
app/src/file.goeshere.txt
