Usage: $(basename "$0") --repos FILE
Run git pull once for every repository listed in FILE. A failure does not
stop the batch. The exit code is 1 if any repository failed.
The script asks for a username and password on the terminal and uses them
for HTTPS remotes. They are not read from the command line or the list file.
Required:
--repos FILE Repository list. One path per line. Blank lines
and lines starting with '#' are ignored. Relative
paths resolve against the directory that contains
FILE.
Other:
-h, --help Show this help
Examples:
$(basename "$0") --repos /srv/proyecto/repos.txt
$(basename "$0") --repos ./repos.txt
