bash first occurrence in log file I looking to write a bash shell script to parse a log file for the first occurance of a date and then once that date is found, the contents of the rest of the log file will be copied to a new file. Here is a simplified example of a log file (test.log) 2010-01-05 .... 2010-01-06 .... 2010-01-07 .... 2010-01-0... 8 Jan 2010 17:18
Q. How do I get bash to respect my physical directory structure? If in bash, I do "set -P" then bash follows the "physical directory structure" when doing "pwd" and "cd .." etc, rather than the "logical one" that might be defined via symlinks.

What's the point of using tar *for backup* today? I see the point of using tar in order to, say, send a whole directory as a single attachment file.

unzip | touch | re-zip Hi, I want to set the file modification times of files stored in a zip file. I think I could work out how to unzip the files to a temporary location, hit them with touch to modify their timestamps, and then store them back in a new zip file that overwrites the original. I then have to clean-up the temporary... 3 Jan 2010 11:36
Redirect stdout and stderr preserving the original order Hi all, There was a question on a web forum on how to redirect stdin and stderr in the following manner: - two separate files for both streams - a third file containing both streams in their original order We haven't come up with a solution and I'm curious to hear your opinion. For instance, let's say we ha... 1 Jan 2010 04:23
