Compare file1 for matching line in file2 and print the difference in matching lines
Hello,

I have two files file 1 and file 2 each having result of a query on certain database tables and need to compare for Col1 in file1 with Col3 in file2, compare Col2 with Col4 and output the value of Col1 from File1 which is a) not present in Col3 of File2 b) value of Col2 is different from Col4:-

File1:
Code:
+-----------------------+-----------+
| Col1 | Col2 |
+-----------------------+-----------+
| Field1 | 20951 |
| Field2 | 65327 |
| Field3 | 89256 |
| Field4 | 56292 |
+----------------------+-----------+
 
Rows = 4

Code:
File 2
+-----------------------+----------+
| Col3 | Col4 |
+-----------------------+----------+
| Field3 | 89256 |
| Field5 | 58754 |
| Field4 | 56101 |
| Field6 | 4578 |
| Field2 | 65301 |
+----------------------+-----------+
 
Rows = 5

Output:
Field1
Field2


Field1 is not there in File2. Filed2 has a different count against it.

I tried using comm for this but it won't work as after sorting File2 still won't match the Fields line by line or won't consider the counts. Another restriction is I have to compare them in shell only.


Any help will be appreciated.

Thanks

lzdiff

XZDIFF(1)							     XZ Utils								 XZDIFF(1)

NAME

       xzcmp, xzdiff, lzcmp, lzdiff - compare compressed files

SYNOPSIS

       xzcmp [cmp_options] file1 [file2]
       xzdiff [diff_options] file1 [file2]
       lzcmp [cmp_options] file1 [file2]
       lzdiff [diff_options] file1 [file2]

DESCRIPTION

       xzcmp  and  xdiff invoke cmp(1) or diff(1) on files compressed with xz(1), lzma(1), gzip(1), or bzip2(1).  All options specified are passed
       directly to cmp or diff.  If only one file is specified, then the files compared are file1 (which must have a suffix of	a  supported  com-
       pression  format)  and  file1 from which the compression format suffix has been stripped.  If two files are specified, then they are uncom-
       pressed if necessary and fed to cmp(1) or diff(1).  The exit status from cmp or diff is preserved.

       The names lzcmp and lzdiff are provided for backward compatibility with LZMA Utils.

SEE ALSO

       cmp(1), diff(1), xz(1), gzip(1), bzip2(1), zdiff(1)

BUGS

       Messages from the cmp(1) or diff(1) programs refer to temporary filenames instead of those specified.
