is there a way to compare two files using diff (ex: diff 1.txt 2.txt) in an if statement?
I read that the exit status of diff is 0 if the files contain the same content. 1 if they're different. So what I am attempting is basically:
i downloaded a text file from metalab.unc.edu called sh.txt and in this reference manual it refers to shell scripting exit status .. at the end of one of the examples that author gave an exit status of 127..
to what does a 127 exit status refer too and what is its purpose in the code.

Hi,
Consider the output of the following commands:
case1)
-------
# ifconfig -a | grep "UP" | grep uplink0:1
# echo $?
Output is: 0
case2
------
# ifconfig -a | grep "UP" | grep uplink0:1; echo $?
Output is: 1
In case2 we got the exit code as 1, which is the actual exit code.... (1 Reply)

I'm preparing for exam and one of exams is to write own test command...
I wonder if in unix is a command which just returns exit code you specify..
I know I can easily write a function like this:
exStatus() {
return $1
}
-> my question is rather theoretical
thank you! (9 Replies)
hi,
exit status variable $?, returns some digits.
0 ---> succes.
1..126
Failure (the program itself will decide what the numbers mean)
127
Command not found
128..254
The program did not exit normally. (E.g., it crashed, or received a signal)
255
Invalid exit code
well, if $?... (4 Replies)

bzcmp
BZDIFF(1) General Commands Manual BZDIFF(1)NAME
bzcmp, bzdiff - compare bzip2 compressed files
SYNOPSIS
bzcmp [ cmp_options ] file1 [ file2 ]
bzdiff [ diff_options ] file1 [ file2 ]
DESCRIPTION
Bzcmp and bzdiff are used to invoke the cmp or the diff program on bzip2 compressed files. All options specified are passed directly to
cmp or diff. If only 1 file is specified, then the files compared are file1 and an uncompressed file1.bz2. If two files are specified,
then they are uncompressed if necessary and fed to cmp or diff. The exit status from cmp or diff is preserved.
