Running the below returns for lines of echoed text, but only the first app from the array actually gets touched:
#!/bin/sh
path=/Applications
app[0]="Microsoft Communicator.app"
app[1]="Microsoft Lync.app"
app[2]="Microsoft Messenger.app"
app[3]="Remote Desktop Connection"
IFS=""
for i in ${app[*]}
do
if [[ -a $path/$app ]];
then
chflags hidden $path/$app;
echo "Hiding $app"
fi;
done
exit
In addition to the basic problem Artur R. Czechowski pointed out, you really should be double-quoting all variable references (and using [@] instead of [*]). This is the proper way to handle variables with spaces; setting IFS will sort of work, but can break other things. Also, you don't need semicolons at the end of lines in bash. Here's my suggested rewrite:
for i in "${app[@]}"
do
if [[ -a "$path/$i" ]] # Double-quotes not strictly needed here, but I consider it a good habit
then
chflags hidden "$path/$i"
echo "Hiding $i"
fi
done
In the loop use $i instead of $app, like below:
for i in ${app[*]}
do
if [[ -a $path/$i ]];
then
chflags hidden $path/$i;
echo "Hiding $i"
fi;
done
