[opensuse] some bash hints, please
I am looking for some bash scripts: 1. I want to list all text files of one directory with a blank line in between. Currently I just use grep "" * 2. I want to delete files older than x (e.g., 3 minutes, 3 hours, 3 days, ...) bye Ronald -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Text files? You mean file.txt, or file with text mime type?
100+1 how to do this.
- ls *.txt
- find . -name "*.txt"
if you need use mime types
try
ls | xargs file {} | grep text

man find, look for TESTS
or somethink like
ls -l | awk ' if($6>"2007-11-06") {print $0}'

find using the -mtime and the -exec option is
more appropriate.

You are listing the content of the files with this command and I don't get a blank line in between. When I want to list the content of ASCII files with the filename preceding each, I use more * > tmp.txt
2. I want to delete files older than x (e.g., 3 minutes, 3 hours, 3 days, ...)
For x in days: find . -mtime +x -print -exec \rm -f '{}' \; For x in minutes change -mtime to -mmin . -- Carlos FL Who is General Failure, and why is he reading my disk? -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

The creation time or date is not kept in Unix, so there's no sure way of knowing how 'old' a file is, only when it was last accessed or modified. Theo -- Theo v.
