UNIX for Dummies Questions & Answers

Hi,

My requirement is :

In our AIX system we have log files like :

Code:

SH1012.LGO
sh123.txt
sh453.txt
sh267.txt
SH1015.LGO
SH1014.LGO

So i just want to reinitialize all files to zero every morning around 1 AM (which are non business hours ...I mean CST timings)

Daily I'm reinitializing them manually as >SH1012.LGO , which is a painful job.

I would like to write cronjob and excute the script to reinitialize all files during 1 AM.

So any idea how to achieve this. ( I know cronjob setting, need script now).

Please use code tags next time for your code and data.

A script is about the same you do on the command line. The commands have just to be written to a file with an editor like vi for example. You then make the script exceutable and assign a cronjob for it. Try it out.

Hi zaxxon,

My point here is , the files will be around 100 and which start with SH10234, I want to clear all files with one command.

I tried with:

Code:

> SH*
 ksh[2]: SH*: 0403-005 Cannot create the specified file.( this getting error while trying to execute the command)

my question is how to reinitialize all files at one go. Hope I'm clear

Use code tags next time for your code and data, thanks!

Code:

for a in SH*; do > $a; done

Great it works.
