Thanks for the advice. I went to using something like,
FILE_LIST=($(ls
'./'$SET'/'$FOLD'/'$FOLD'_anneal/'$PARAM_SET'/'$AN_SET'/'*'out.txt' ))
instead of,
FILE_LIST='./'$SET'/'$FOLD'/'$FOLD'_anneal/'$PARAM_SET'/'$AN_SET'/'*'out.txt'
when I was creating a script because ls will throw an exception if there
is nothing found matching the glob. This is especially true when I am
using a long path with allot of variables. I often remove the ls once I
know the script is working. The the first syntax above also creates an
array.
FILE_DIR was assigned separately because it it used in some other places
in the script and convenient to have in scope.
I have also had problems evaluating strings that were created by
assigning with a glob.
If I had a file,
myfile_1.txt
and did,
file_name='myfile_'*'.txt'
and then,
if [ "$file_name" = "myfile_1.txt" ];
I have had issues getting the above conditional to evaluate as true.
If instead I do,
file_name=$(ls 'myfile_'*'.txt')
the conditional will evaluate properly.
Am I mistaken about this? I have not taken the time to run down all of
these issues when they occur, which I really should.
