问题
In Bash (or other shells) how can I print an environment variable which has a multi-line value?
text='line1
line2'
I know a simple usual echo $text won't work out of the box.
Would some $IFS tweak help?
My current workaround is something like ruby -e 'print ENV["text"]'.
Can this be done in pure shell? I was wondering if env command would take an unresolved var name but it does not seem to.
回答1:
Same solution as always.
echo "$text"
回答2:
export TEST="A\nB\nC"
echo $TEST
gives output:
A\nB\nC
but:
echo -e $TEST
A
B
C
So, the answer seems to be the '-e' parameter to echo, assuming that I understand your question correctly.
