UNIX for Dummies Questions & Answers

Hi,

I have a file a.txt, I am moving the file from my source location (/root/onw/src) to target folder(root/byl/src). My target folder has already a file by name a.txt..,while moving can I see if this file a.txt is existing then move it to archive folder(/root/byl/arc) zip and add time stamp to the zip folder.

Thx,Shruthi

What did you try so far? Where did you get stuck?

HI ,

I am doing a gzip as

Code:

gzip ABC.csv

which is creating a zip file and with the below code I am attaching a time stamp value to the zip file .

Code:

timestamp=$( date +%d%m%y%H%M%S )
mv A*.gz filename"$timestamp"

first time as their is only one file it is appending the time stamp but when I am executing this for the second time it is adding timestamp for the file which has the timestamp

daily I will be compressing one file and adding the time stamp, so second day the timestamp should be added to the new file and it should not add timestamp to any file which has the time stamp.
