I hope you can help me and thank you in advance for any help you may give As you can see, the key command is 'wc'. It's a nice, simple little command that does one thing and one thing well - it counts "words". If you don't give it any flags, it tells you the number of lines, words, and bytes. Using -l will count the number of lines. So you pipe the output of a command to it and it will count stuff for you. Thus: $ ls db* |wc -l will give you a single number telling you the number of lines in its input; in this case, the input is the output of 'ls db*', which is a simple listing of all the files in the current directory beginning with 'db'. Thus, you get a count of the number of files in the directory that begin with db. A very typical Un*x way of doing things - string together building block commands to get your output.

Be careful in case that directory contains subdirectories, since 'find' will traverse them by default as well. If you want to count files only in the directory level of '/path/to/dir' you may want to add '-maxdepth 1', like so: find /path/to/dir -type f -name db\* -maxdepth 1 -print | wc -l Uwe -- Uwe Doering | EscapeBox - Managed On-Demand UNIX Servers [EMAIL PROTECTED] | http://www.escapebox.net ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
