Then you should change the script to the below  or 

1) Files='DKC Lab 

               postcr

echo $Files.

 

2) don't use any script use echo "what you want" 😝.  If you have automated process add subject "job completed with no issues"

for loop considers "spaces" as a seperator for input. Your file "DKC Lab" has space in it. Can't you just rename such files?

just add this to your script at the top "IFS=$'\n'" and put all the files in a temp file (temp_file.txt) and run 

 

your temp file containing file names:

cat temp_file.txt
DKC Lab
postcr

your script:

IFS=$'\n'
for file in `cat temp_file.txt`; do echo $file;done
DKC Lab
postcr
