Shell Programming and Scripting

Hello Unix forum.

I'm encountering the following error "binary operator expected error" and I cannot seem to solve the issue.

I have the following source files to process:
CPA_LOOKUP_dat.lst
PROFILE_TXN_[0-9]_dat.lst
TRANSACTION_CODE_dat.lst
PROFILE_TXN_OUT_OF_BALANCE_dat.lst

and here's a sample of my code:

Code:

.....
  if [ -e ${LST_SRC_DIR}/${source_filename}*${DATLST} ] &&
      [ ${error_flag} == "FALSE" ]
   then
       archive_data_files
   fi
.....
Where LST_SRC_DIR = /data
DATLST=_dat

All files are processed okay until the file PROFILE_TXN_[0-9]_dat.lst - then I get the following error:

line 418: [: /data/informatica/ming/SrcFiles/ACCTTXNLST/PROFILE_TXN_[0-9]_dat.lst: binary operator expected


Can someone help me out and improve my code to successfully process all of the files?

Thank you

That looks like the pattern is expanded to several filenames which [ -e can't handle. The error msg only prints the first name. Make sure you only process one single name at a time.

Thanks Rudi for your reply.

You are absolutely correct.

I had 2 files staring with the same prefix:

PROFILE_TXN_[0-9]_dat.lst
PROFILE_TXN_OUT_OF_BALANCE_dat.lst
