I need to compare 2 files. I need to see if 1 file has records that are not in a second file. I did some searching and found the 'comm' command. According to the man pages
Will tell me what is in file 1 and not in file 2. So I did a simple test
test1.txt has the following data
test2.txt
It looks like comm doesn't work if the fields are ordered differently. How do I do this?

Reason: Please wrap data examples with CodeTags also.
See my other post on sdiff ....
I don't think sdiff is able to do what I want.
The 'comm' command does what I need and works fine as
far as the logic and results.
The problem I'm having is with the output format, it outputs 3 columns of data,
but because of the way it starts each line... (2 Replies)

The manual does not cover this very well. What do the following compares will do ?

bup-restore
bup-restore(1) General Commands Manual bup-restore(1)NAME
bup-restore - extract files from a backup set
SYNOPSIS
bup restore [--outdir=outdir] [-v] [-q]
DESCRIPTION
bup restore extracts files from a backup set (created with bup-save(1)) to the local filesystem.
The specified paths are of the form /branch/revision/path/to/file. The components of the path are as follows:
branch the name of the backup set to restore from; this corresponds to the --name (-n) option to bup save.
revision
the revision of the backup set to restore. The revision latest is always the most recent backup on the given branch. You can dis-
cover other revisions using bup ls /branch.
/path/to/file
the original absolute filesystem path to the file you want to restore. For example, /etc/passwd.
Note: if the /path/to/file is a directory, bup restore will restore that directory as well as recursively restoring all its contents.
If /path/to/file is a directory ending in a slash (ie. /path/to/dir/), bup restore will restore the children of that directory directly to
the current directory (or the --outdir). If the directory does not end in a slash, the children will be restored to a subdirectory of the
current directory. See the EXAMPLES section to see how this works.
OPTIONS -C, --outdir=outdir
create and change to directory outdir before extracting the files.
-v, --verbose
increase log output. Given once, prints every directory as it is restored; given twice, prints every file and directory.
-q, --quiet
don't show the progress meter. Normally, is stderr is a tty, a progress display is printed that shows the total number of files
restored.
EXAMPLE
Create a simple test backup set:
$ bup index -u /etc
$ bup save -n mybackup /etc/passwd /etc/profile
Restore just one file:
$ bup restore /mybackup/latest/etc/passwd
Restoring: 1, done.
$ ls -l passwd
-rw-r--r-- 1 apenwarr apenwarr 1478 2010-09-08 03:06 passwd
Restore the whole directory (no trailing slash):
$ bup restore -C test1 /mybackup/latest/etc
Restoring: 3, done.
$ find test1
test1
test1/etc
test1/etc/passwd
test1/etc/profile
Restore the whole directory (trailing slash):
$ bup restore -C test2 /mybackup/latest/etc/
Restoring: 2, done.
$ find test2
test2
test2/passwd
test2/profile
