Hi Sathyaonunix

Dear sathyaonunix,
Consider that the pattern that you have changed are different ie., say
XXX1
XXX2
XXX3

and these might be the contents of a file say file2.txt
now can you please help me to replace the pattern Sathya in file1 with the three patterns of file2.txt.

And what if the contents of file1 that contains
nl file 1 Sathya 2 Sathya 3 Sathya 4 Sathya 5 SAthya 6 Narayanan 7 Narayanan 8 Sathya 9 Sathya 10 Narayanan might not have a key and might be arranged in a singel line like this,
sathya sathya sathya sathya sathya Narayanan Narayanan Sathya sathya Narayanan

Please suggest me how to replace if we encounter such a problem,

Thanks,
Kashyap.



Thanks,
Kashyap.

NAME
xzcmp, xzdiff, lzcmp, lzdiff - compare compressed files SYNOPSIS
xzcmp [cmp_options] file1 [file2] xzdiff [diff_options] file1 [file2] lzcmp [cmp_options] file1 [file2] lzdiff [diff_options] file1 [file2] DESCRIPTION
xzcmp and xdiff invoke cmp(1) or diff(1) on files compressed with xz(1), lzma(1), gzip(1), or bzip2(1). All options specified are passed directly to cmp or diff. If only one file is specified, then the files compared are file1 (which must have a suffix of a supported com- pression format) and file1 from which the compression format suffix has been stripped. If two files are specified, then they are uncom- pressed if necessary and fed to cmp(1) or diff(1). The exit status from cmp or diff is preserved. The names lzcmp and lzdiff are provided for backward compatibility with LZMA Utils. SEE ALSO
cmp(1), diff(1), xz(1), gzip(1), bzip2(1), zdiff(1) BUGS
Messages from the cmp(1) or diff(1) programs refer to temporary filenames instead of those specified. Tukaani 2009-07-05 XZDIFF(1)
