Top Forums Shell Programming and Scripting appending data from similar files Post 302580549 by mrbean1975 on Thursday 8th of December 2011 10:30:46 PM

Sorry, I should have been more specific...I am not sure how many such patterns exist. In other words, it could be file1_*, file2_*, file3_* ...filen_*
how can I do this dynamically?
The actual situation in my case is the timestamp is appended to file1, file2, etc. I would like to combine all such (file1_*, file2_*) from a current day (or whatever the correct range of files I determine) to be appended into one file. But if I get a general idea, I can proceed with the actual implementation, except that I am stuck how to do this dynamically.

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)
