In the assignment, remove space between variable name and =
TAGS="${TAGS}${item}"
質問
I'm trying to loop over all environment variables in a shell script, and create an HTML query string from ones which match a pattern. Unfortunately, I can't seem to assign to variables in the loop. I've got this:
#!/bin/sh
IFS=$'\n'
TAGS=""
for item in $(printenv)
do
if [[ $item == FOO_TAG_* ]]
then
TAGS = "${TAGS}&${item}"
fi
done
But this gives me
/etc/script.sh: line 9: TAGS: command not found
/etc/script.sh: line 9: TAGS: command not found
How do I fix this?
