From b469b65f0110f09dec06a7061975947647716332 Mon Sep 17 00:00:00 2001 From: Kevin Lyda Date: Tue, 29 Aug 2017 08:12:44 +0100 Subject: [PATCH] Fix version processing on BSD systems. BSD systems ship with the original sed; lacking a host of GNU extensions. However both GNU sed and POSIX sed support the -E flag for extended regular expressions which are close to the change this is replacing. See the descriptions of extended REs in IEEE Std 1003.2 (aka POSIX.2) or re_format(7) on BSD systems. What matters for this is that the + operator works and that it and the grouping operators no longer need to be escaped. --- vcsh | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) diff --git a/vcsh b/vcsh index f06f5b4..d1d26ed 100755 --- a/vcsh +++ b/vcsh @@ -166,7 +166,7 @@ clone() { You should add files to your new repository." exit fi - GIT_VERSION_MAJOR=$(git --version | sed -n 's/.* \([0-9]\+\)\..*/\1/p' ) + GIT_VERSION_MAJOR=$(git --version | sed -E -n 's/.* ([0-9]+)\..*/\1/p' ) if [ 1 -lt "$GIT_VERSION_MAJOR" ];then git fetch origin "$VCSH_BRANCH" else @@ -482,8 +482,8 @@ write_gitignore() { use cd "$VCSH_BASE" || fatal "could not enter '$VCSH_BASE'" 11 local GIT_VERSION="$(git --version)" - local GIT_VERSION_MAJOR=$(echo $GIT_VERSION | sed -n 's/.* \([0-9]\+\)\..*/\1/p') - local GIT_VERSION_MINOR=$(echo $GIT_VERSION | sed -n 's/.* \([0-9]\+\)\.\([0-9]\+\)\..*/\2/p') + local GIT_VERSION_MAJOR=$(echo $GIT_VERSION | sed -E -n 's/.* ([0-9]+)\..*/\1/p') + local GIT_VERSION_MINOR=$(echo $GIT_VERSION | sed -E -n 's/.* ([0-9]+)\.([0-9]+)\..*/\2/p') OLDIFS=$IFS IFS=$(printf '\n\t') gitignores=$(for file in $(git ls-files); do -- 2.39.2
