Output is same, and it always echos need to pull.
If I remove the quotes around $text in if condition it throws the too many arguments error.
var="$(git status -uno)" &&
text="On branch master Your branch is up-to-date with 'origin/master'. nothing to commit (use -u to show untracked files)";
echo $var;
echo $text;
if [ "$var" = "$text" ]; then
echo "Up-to-date"
else
echo "need to pull"
fi
Better do this, =~ for bash regex :
#!/bin/bash
var="$(git status -uno)"
if [[ $var =~ "nothing to commit" ]]; then
echo "Up-to-date"
else
echo "need to pull"
fi
or
#!/bin/bash
var="$(git status -uno)"
if [[ $var == *nothing\ to\ commit* ]]; then
echo "Up-to-date"
else
echo "need to pull"
fi
Warning: bash's regex require more ressources and won't work in other shell!
This syntax is POSIX compatible, not bash only!
if LANG=C git status -uno | grep -q up-to-date ; then
echo "Nothing to do"
else
echo "Need to upgrade"
fi
From this answer to How to check if a string contains a substring in Bash, here is a compatible syntax, working under any standard POSIX shell:
#!/bin/sh
stringContain() { [ -z "${2##*$1*}" ] && { [ -z "$1" ] || [ -n "$2" ] ;} ; }
var=$(git status -uno)
if stringContain "up-to-date" "$var" ;then
echo "Up-to-date"
# Don't do anything
else
echo "need to pull"
# Ask for upgrade, see:
fi
git statusis not a single line of text. In general, this is a very brittle approach to scripting git – there is no guarantee that the output ofgit statusdoesn't change between git versions. A better approach would be usinggit status --porcelain(see docs).git status -unoagainst an up to date branch the return fromgit statushas line feeds in it. Those don't seem to be accounted for in your$textvariable.
