I'm not very familiar with the ssh command. When I tried to set a variable and then echo its value on a remote machine via ssh, I found a problem. For example,
$ ITSME=itsme
$ ssh xxx.xxxx.xxx.xxx "ITSME=itsyou; echo $ITSME"
itsme
$ ssh xxx.xxxx.xxx.xxx 'ITSME=itsyou; echo $ITSME'

cmp
cmp(1) User Commands cmp(1)NAME
cmp - compare two files
SYNOPSIS
cmp [-l] [-s] file1 file2 [skip1] [skip2]
DESCRIPTION
The cmp utility compares two files. cmp will write no output if the files are the same. Under default options, if they differ, it writes to
standard output the byte and line numbers at which the first difference occurred. Bytes and lines are numbered beginning with 1. If one
file is an initial subsequence of the other, that fact is noted. skip1 and skip2 are initial byte offsets into file1 and file2 respec-
tively, and may be either octal or decimal; a leading 0 denotes octal.
OPTIONS
The following options are supported:
-l Write the byte number (decimal) and the differing bytes (octal) for each difference.
-s Write nothing for differing files; return exit statuses only.
OPERANDS
The following operands are supported:
file1 A path name of the first file to be compared. If file1 is -, the standard input will be used.
file2 A path name of the second file to be compared. If file2 is -, the standard input will be used.
If both file1 and file2 refer to standard input or refer to the same FIFO special, block special or character special file, an error
results.
USAGE
See largefile(5) for the description of the behavior of cmp when encountering files greater than or equal to 2 Gbyte (2**31 bytes).
EXAMPLES
Example 1: Comparing files byte for byte
The following example:
example% cmp file1 file2 0 1024
does a byte for byte comparison of file1 and file2. It skips the first 1024 bytes in file2 before starting the comparison.
ENVIRONMENT VARIABLES
See environ(5) for descriptions of the following environment variables that affect the execution of cmp: LANG, LC_ALL, LC_CTYPE, LC_MES-
SAGES, and NLSPATH.
EXIT STATUS
The following error values are returned:
0 The files are identical.
1 The files are different; this includes the case where one file is identical to the first part of the other.
>1 An error occurred.
