Shell Programming and Scripting

Hello I need to alter a script to check for a flag file but there are now more than one type of flag file in my directory. Basically if any of these flg files exist then the MASK value should be set? Flag files to be included in assignment to variable
e2e_scheduled*.flg
COLL_STOP*.flg
contracted_coll*.flg


Original assignment


MASK=*.flg

New assignment would this work?


MASK = e2e_scheduled*.flg, COLL_STOP*.flg,contracted_coll*.flg

I'm a little unclear what you are trying to acheive. Here are my thoughts on what I think you may be looking for:-

Is it just to detect if a file of that name exists?

Code:

if [ -r *.flg ]
then
   echo "Hit"
else
   echo "Miss"
fi

If you want a list of files to loop through:-

Code:

for file in *.flg
do
   MASK=1     # Or whatever you want to set it to
   whatever
done

If you want to assign all the names for files to the variable MASK comma seaparated:-

Code:

for file in *.flg
do
   MASK="$MASK,$file"
done
MASK="${MASK#,}"          # Remove leading comma

Am I anywhere near your requirement?
