Running a conditional script in bash [duplicate]

Question

This is the code I'm using to check the current git branch,

branch=$(git branch | sed -n -e 's/^\* \(.*\)/\1/p')

I want to run the following code conditionally if the branch is master

cd build && aws s3 cp . s3://www.examle.com/ --recursive

How do I do this in bash?

As in most languages you would use an if statement. Look them up in your favorite bash language reference — that other guy

BTW, I'd maybe make it (cd build && exec aws s3 ...) -- adding the exec balances out the performance impact of the subshell created by the parens (by consuming it), while scoping the cd to only change the directory where that one aws s3 command is run. — Charles Duffy

branch=$(git branch | sed -n -e 's/^\* \(.*\)/\1/p')
if [ "$branch" = master ]; then
   cd build && aws s3 cp . s3://www.examle.com/ --recursive

Try like below

[[ "$branch" == master ]] && cd build && aws s3 cp . s3://www.examle.com/ --recursive
