Question Escaping square brackets when defining a Csh list

Hi All,

I was trying to define a Csh list where one string item contains square brackets, I escaped them as follows in order not to get "No match" error:

Code:
set LIST = {a,b\[2\],c,d}
foreach ITEM ($LIST)
   echo $ITEM
end

In this case foreach gives "No match" error, which makes sense. Using 3 escape characters /// instead of one didn't solve the issue, and neither did using the quotations "".

Any help would be much appreciated.

Thanks,

Hi,

below is in 'bash'.

Code:
#!/bin/sh

LIST=(a b\[2\] c d)
for ITEM  in ${LIST[*]}
do
   echo $ITEM
done

you must not use the either of escape chars at the same time

Code:
#!/bin/csh
foreach ITEM ( a b\[2\] c d )
   echo "$ITEM"
end

or

Code:
#!/bin/csh
foreach ITEM ( a "b[2]" c d )
   echo "$ITEM"
end

Thanks alot ygemici and chirel, I've tried this already; using / and " and using them together.. all works in the foreach statement Smilie but my real problem is that I need to define a list and use it with "foreach" like:

Code:
set LIST = xxxxxxxx #where $LIST holds the items a, b[2]... blabla
foreach ITEM ($LIST)
echo "$ITEM"
end

How can I define such list?

Thanks,

Code:
#!/bin/csh
set LIST= ( a b[2"]" c d ) ; echo "$LIST[*]" >tmpX
foreach ITEM ( `cat tmpX` )
 echo "$ITEM"
end
a
b[2]
c
d
