Top Forums UNIX for Advanced & Expert Users improve performance by using ls better than find Post 48375 by Perderabo on Friday 5th of March 2004 05:33:53 AM

find /dir1 -name '*.[nN][sS][fF]' -print

will be much faster. Your command is launching a "ls" process for each file that it finds. But searching a large collection of files is going to take some time.

And the find command will beat any ls -R command. Remember that ls will sort the output while find does not.

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

NAME
shar -- create a shell archive of files SYNOPSIS
shar file ... DESCRIPTION
The shar command writes a sh(1) shell script to the standard output which will recreate the file hierarchy specified by the command line op- erands. Directories will be recreated and must be specified before the files they contain (the find(1) utility does this correctly). The shar command is normally used for distributing files by ftp(1) or mail(1). 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 SEE ALSO
compress(1), mail(1), tar(1), uuencode(1) HISTORY
The shar command appeared in 4.4BSD. BUGS
The shar command makes no provisions for special types of files or files containing magic characters. The shar command cannot handle files without a newline (' ') as the last character. 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 BSD
