cmp - compare two files byte by byte
SYNOPSIS
cmp [OPTION]... FILE1 [FILE2 [SKIP1 [SKIP2]]]
DESCRIPTION
Compare two files byte by byte.
-b--print-bytes
Print differing bytes.
-i SKIP --ignore-initial=SKIP
Skip the first SKIP bytes of input.
-i SKIP1:SKIP2 --ignore-initial=SKIP1:SKIP2
Skip the first SKIP1 bytes of FILE1 and the first SKIP2 bytes of FILE2.
-l--verbose
Output byte numbers and values of all differing bytes.
-n LIMIT --bytes=LIMIT
Compare at most LIMIT bytes.
-s--quiet--silent
Output nothing; yield exit status only.
-v--version
Output version info.
--help Output this help.
SKIP1 and SKIP2 are the number of bytes to skip in each file. SKIP values may be followed by the following multiplicative suffixes: kB
1000, K 1024, MB 1,000,000, M 1,048,576, GB 1,000,000,000, G 1,073,741,824, and so on for T, P, E, Z, Y.
If a FILE is `-' or missing, read standard input. Exit status is 0 if inputs are the same, 1 if different, 2 if trouble.

Friends,
I have two very large plain text files with pipe delimited as below.
Both files are not sorted.
Both files have 200,000 of rows.

Is perl or shell script feasible for this task?
Thanks,

Hi,
Here is a tough requirement , to be served by bash script.
I want to perform 3,00,000 * 10,000 searches.
i.e. I have 10,000 doc files and 3,00,000 html files in the file-system. I want to check, which of the doc files are referred in any html files. (ex- <a href="abc.doc">abc</a>)... (3 Replies)

I have a file with numbers in US notation (1,000,000.00) as well as european notation (1.000.000,00)
i want all the numbers to be in european notation.

sed 's/,/\./'... (2 Replies)
I have a file in two columns consisting of only numbers. I would like to put a string (the same textstring) on every second line, so that
501006 420.000
401602 165.000
.
.
.
becomes:
*Some_text
501006 420.000
*Some_text
401602 165.000
*Some_text

Are you up for it? (7 Replies)
