expr / awk / sed：从仓库URL获取git目录名称

Question

Using bash expr , sed or awk , how can I determine the git base directory for a given git repo?

For example: git@git.gitweb.com:/myModule-repo.git => myModule-repo

Answer 1

If you insist on doing that with these tools,

echo git@git.gitweb.com:/myModule-repo.git | sed 's%^.*/\([^/]*\)\.git$%\1%g'

(find the substring from the last / until the literary .git) should do the trick, otherwise I would use

basename git@git.gitweb.com:/myModule-repo.git .git

which does the same (also, it is much more transparent and basename is as POSIX as sed and awk ).

Answer 2

echo "git@git.gitweb.com:/myModule-repo.git" | sed 's|git@git.gitweb.com:/||;s/.git//'

Answer 3

echo git@git.gitweb.com:/myModule-repo.git | awk 'BEGIN {FS="/"} {print substr ($2, 1, 13)}'
