Finding matching patterns in two files

Hi,

I have requirement to find the matching patterns of two files in Unix. One file is the log file and the other is the error list file. If any pattern in the log file matches the list of errors in the error list file, then I would need to find the counts of the match.

For example,

Log file has the below information:

Code:

sftp> cd /home/development/project
sftp> MPUT ABCD_*.zip
Uploading ABCD_20150220_20150220012345.zip to /home/development/project/ABCD_20150220_20150220012345.zip
Couldn't get handle: Permission denied

error list file has the below information:

Code:

12,Permission denied,FTP error
14,No connection,Conection error

As "Permission denied" matches in both the files, the output count should be 1.

I tried to use grep -Ff option but I am getting the below error:

grep: illegal option -- F
grep: illegal option -- f
Usage: grep -hblcnsviw pattern file . . .

Please help

zegrep

ZGREP(1)						    BSD General Commands Manual 						  ZGREP(1)

NAME

     zgrep, zegrep, zfgrep -- print lines matching a pattern in gzip-compressed files

SYNOPSIS

     zgrep [grep-flags] [--] pattern [files ...]

     zegrep [grep-flags] [--] pattern [file ...]

     zfgrep [grep-flags] [--] pattern [file ...]

DESCRIPTION

     zgrep runs grep(1) on files or stdin, if no files argument is given, after decompressing them with zcat(1).

     The grep-flags and pattern arguments are passed on to grep(1).  If an -e flag is found in the grep-flags, zgrep will not look for a pattern
     argument.

     zegrep calls egrep(1), while zfgrep calls fgrep(1).

EXIT STATUS

     In case of missing arguments or missing pattern, 1 will be returned, otherwise 0.

SEE ALSO
