making a .tar with a string and a variable name

Anthraxnz · 11-03-2006, 02:23 AM

i need to make a .tar file named "backp_<date>.tar" date being the actual date.

i got this so far:

Code:

DATE=`date +%D` // gets date in format of 11/3/06

i need to make this part work.

Code:

tar -cf backup_$DATE.tar $FILE  //File Being the file or dir name to backup

this is for a shell script, i tried lots of different ways but cant get it to work.

Thanks
Anthrax

Hi,

The forward slashes in your string cause problems, it's one of the special characters.
Try not using them, they need to be escaped every time you want to do something with that string (or the created file).

Something like this works:

DATE=`date '+%m-%d-%y'` => Date format will be: 11-03-06
tar -cf backup_$DATE.tar $FILE => filename will be: backup_11-03-06.tar

Hope this helps.
