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.

SHAR(1) 						    BSD General Commands Manual 						   SHAR(1)

NAME
shar -- create a shell archive of files SYNOPSIS
shar file ... DESCRIPTION
shar writes an sh(1) shell script to the standard output which will recreate the file hierarchy specified by the command line operands. Directories will be recreated and must be specified before the files they contain (the find(1) utility does this correctly). shar is normally used for distributing files by ftp(1) or mail(1). SEE ALSO
compress(1), mail(1), tar(1), uuencode(1) BUGS
shar makes no provisions for special types of files or files containing magic characters. EXAMPLES
To create a shell archive of the program ls(1) and mail it to Rick: cd ls shar `find . -print` | mail -s "ls source" rick To recreate the program directory: mkdir ls cd ls ... <delete header lines and examine mailed archive> ... sh archive HISTORY
The shar command appears in 4.4BSD. SECURITY CONSIDERATIONS
It is easy to insert trojan horses into shar files. It is strongly recommended that all shell archive files be examined before running them through sh(1). Archives produced using this implementation of shar may be easily examined with the command: egrep -v '^[X#]' shar.file 4.4BSD June 6, 1993 4.4BSD
