I have got 2 files which i need to compare and append based on the below conditions.
file 1:
File 1 has data in the following format
File 2 has data in the same fomat
Now i need to compare the first 4 bytes in each line from file2 and see if it exists on file1, and if they match ( they may be present in any position), i need to append the values present in pos6 onwards in sorted order
For example, for the number 4300 the value should come as
4300 234569
and if the number in the 1st 4 bytes of file 2 is not found in file 1 , i need to append the whole line to file 1.
How can this be done......need help....anyone plzzz

Hi, all:
I've got two folders, say, "folder1" and "folder2".
Under each, there are thousands of files.
It's quite obvious that there are some files missing in each. I just would like to find them. I believe this can be done by "diff" command.
However, if I change the above question a... (1 Reply)

Hi,
I'm a newbie to scripting and am trying to compare two files using awk.
The files are exactly the same dimensions. Where the first file has 0's I would like to create an updated version of the second file which has the corresponding elements set to zero also.
eg:

I have this code
awk 'NR==FNR{a=$1;next} a' file1 file2
which does what I need it to do, but for only two files. I want to make it so that I can have multiple files (for example 30) and the code will return only the items that are in every single one of those files and ignore the ones... (7 Replies)

opendiff
opendiff(1) BSD General Commands Manual opendiff(1)NAME
opendiff -- Use FileMerge to graphically compare or merge file or directories
SYNOPSIS
opendiff file1 file2 [-ancestor ancestorFile] [-merge mergeFile]
opendiff dir1 dir2 [-ancestor ancestorDirectory] [-merge mergeDirectory]
DESCRIPTION
opendiff is a command line utility that provides a convenient way to launch the FileMerge application from Terminal to graphically compare
files or directories. If FileMerge is already running, opendiff will connect to that running instance for the new comparison. opendiff
exits immediately after the comparison request has been sent to FileMerge.
opendiff and FileMerge can be used to compare two files file1 and file2 or to compare two directories dir1 and dir2.
If the -ancestor flag is given, FileMerge will compare the two files or directories to a common ancestor. This is useful if two people inde-
pendently modify copies of a single original file or directory.
FileMerge lets you merge two files or directories together to create a third file or directory. To see the contents of a merged file, drag
the splitter bar at the bottom of FileMerge's file comparison window. The contents of the merged file can be directly edited within File-
Merge. After editing, the merged file can be saved to the file (or into the directory) specified with the Fl merge flag. If a destination
is not specified with the -merge flag, FileMerge will ask for a destination file or directory when you try to save a merged file.
For further information, please consult the Help information available from the FileMerge application.
