Subject: why isn't IFS=$'\n' doing what I expect it to do here?
Date: Sat, 23 Mar 2013 22:01:14 -0400 [thread overview]
Message-ID: <CADjGqHsO-Ysi5KWwLU_SwkGJubcMsM-rFmBvfHw7Fq5ZsuyErg@mail.gmail.com> (raw)
I don't understand why IFS=$'\n' doesn't seem to be doing what I'd expect here:
$ cat test-arrays.zsh
IFS=$'\n' APPS=(
Alfred 2
Bartender
ddnsa
Fantastical
Flycut
HazelHelper
MagiCal
MenuBarFilter
Mountain
Should I Sleep
SizeUp
Trickster
)
echo "5 is: $APPS[5]"
for f in $APPS
do
echo ">$f<"
done
(Result of the command is)
5 is: Fantastical
>Alfred<
>2<
>Bartender<
>ddnsa<
>Fantastical<
>Flycut<
>HazelHelper<
>MagiCal<
>MenuBarFilter<
>Mountain<
>Should<
>I<
>Sleep<
>SizeUp<
>Trickster<
I thought that IFS=$'\n' would make it so I didn't have to escape the
spaces in the lines which had them.
If I take OUT the IFS line and escape the spaces, it works as I'd expect
APPS=(
Alfred\ 2
Bartender
ddnsa
Fantastical
Flycut
HazelHelper
MagiCal
MenuBarFilter
Mountain
Should\ I\ Sleep
SizeUp
Trickster
)
echo "5 is: $APPS[5]"
for f in $APPS
do
echo ">$f<"
done
(Result of the command is)
5 is: Flycut
