So the output from sdiff looks like the output from diff -y to me. I've not seen any options in them or comm that would help.
It depends what you are trying to achieve on how we approach this. They all just want two files, so I'm hoping you either know the file names or use variable in a script to run sdiff already.
You might have some joy with something like:-
It's not pretty, but that might give you what you need.
If this doesn't deliver, can you show us some sample input and desired output along with any thing you have tried and why they do not give you what you want.
Hello,
I'm using Sdiff to compare 2 files, I've used this before and it works fine
and still does in some cases.
But it seems to trip up when using combinations of alpha-numeric text.
I created two simple files to test and as you can see it seems to trip up
on the "gr55a" text, any ideas ?

Hi all
I have two files which are essentially the same. However the way an exponent is written is different (i.e. in 1 file, a particular number might be written as 1.43230000E+02 whereas in another it might be 1.4323E2).
If I use SDIFF then the program will merely check the ASCII characters... (1 Reply)

Im using the vmstat command to display the CPU run queue, but i want to put that into a program so is there a way to just display the number under the r?

Hi,
I'm trying to use sdiff by parsing the output of another command instead of the filename:
sdiff <(echo test1) <(echo test2)However, this seems to cause my terminal session to stop working.
If I use it with normal diff it works fine:
~$ diff <(echo test1) <(echo test2)

sdiff - find differences between two files and merge interactively
SYNOPSIS
sdiff -o outfile [options] from-file to-file
DESCRIPTION
The sdiff command merges two files and interactively outputs the results to outfile.
If from-file is a directory and to-file is not, sdiff compares the file in from-file whose file name is that of to-file, and vice versa.
from-file and to-file may not both be directories.
sdiff options begin with -, so normally from-file and to-file may not begin with -. However, -- as an argument by itself treats the
remaining arguments as file names even if they begin with -. You may not use - as an input file.
sdiff without -o (or --output) produces a side-by-side difference. This usage is obsolete; use diff --side-by-side instead.
Options
Below is a summary of all of the options that GNU sdiff accepts. Each option has two equivalent names, one of which is a single letter
preceded by -, and the other of which is a long name preceded by --. Multiple single letter options (unless they take an argument) can be
combined into a single command line argument. Long named options can be abbreviated to any unique prefix of their name.
-a Treat all files as text and compare them line-by-line, even if they do not appear to be text.
-b Ignore changes in amount of white space.
-B Ignore changes that just insert or delete blank lines.
-d Change the algorithm to perhaps find a smaller set of changes. This makes sdiff slower (sometimes much slower).
-H Use heuristics to speed handling of large files that have numerous scattered small changes.
--expand-tabs
Expand tabs to spaces in the output, to preserve the alignment of tabs in the input files.
-i Ignore changes in case; consider upper- and lower-case to be the same.
-I regexp
Ignore changes that just insert or delete lines that match regexp.
--ignore-all-space
Ignore white space when comparing lines.
--ignore-blank-lines
Ignore changes that just insert or delete blank lines.
--ignore-case
Ignore changes in case; consider upper- and lower-case to be the same.
--ignore-matching-lines=regexp
Ignore changes that just insert or delete lines that match regexp.
--ignore-space-change
Ignore changes in amount of white space.
-l
--left-column
Print only the left column of two common lines.
--minimal
Change the algorithm to perhaps find a smaller set of changes. This makes sdiff slower (sometimes much slower).
-o file
--output=file
Put merged output into file. This option is required for merging.
-s
--suppress-common-lines
Do not print common lines.
--speed-large-files
Use heuristics to speed handling of large files that have numerous scattered small changes.
-t Expand tabs to spaces in the output, to preserve the alignment of tabs in the input files.
--text Treat all files as text and compare them line-by-line, even if they do not appear to be text.
-v
--version
Output the version number of sdiff.
-w columns
--width=columns
Use an output width of columns. Note that for historical reasons, this option is -W in diff, -w in sdiff.
-W Ignore horizontal white space when comparing lines. Note that for historical reasons, this option is -w in diff, -W in sdiff.
SEE ALSO cmp(1), comm(1), diff(1), diff3(1).
DIAGNOSTICS
An exit status of 0 means no differences were found, 1 means some differences were found, and 2 means trouble.
