bash script to increment a digit in filename

hbjlee17 · #1 03-14-2010

Hi guys,

Can someone help me out with this:

I have a directory with files like the following,
GHost++ 2010-03-14 04-01 DotaCash RD us_ca LC #7 (44m19s).w3g
GHost++ 2010-03-14 04-06 DotaCash AP us_ca LC #8 (42m24s).w3g
GHost++ 2010-03-14 04-07 DotaCash AR us_ca LC #10 (08m23s).w3g
GHost++ 2010-03-14 04-13 DotaCash AR us_ca LC #8 (48m17s).w3g
GHost++ 2010-03-14 04-15 DotaCash RD us_ca LC #9 (45m17s).w3g

I would like to know how to add to the hour part of the filename for all the files in that direction. In this particular example, add 3 to 04, so it becomes 07.

end result would be something like this.
GHost++ 2010-03-14 07-01 DotaCash RD us_ca LC #7 (44m19s).w3g
GHost++ 2010-03-14 07-06 DotaCash AP us_ca LC #8 (42m24s).w3g
GHost++ 2010-03-14 07-07 DotaCash AR us_ca LC #10 (08m23s).w3g
GHost++ 2010-03-14 07-13 DotaCash AR us_ca LC #8 (48m17s).w3g
GHost++ 2010-03-14 07-15 DotaCash RD us_ca LC #9 (45m17s).w3g

Any help is greatly appreciated.

Thanks.,

Code:

ls GHost++ 2010-03-14 04-* |
awk -F'[ -1]'  '{ old=$0; $5+=3; system( sprintf("mv %s %s",old, $0) ) } '

Hi thanks for the quick response.
It did not work...

Code:

 
ls GHost++\ `date +%Y-%m-%d`* | awk -F'[ -1]'  '{ old=$0; $5+=3; system( sprintf("mv %s %s",old, $0) ) } '

Thanks.

Getting closer, however, the 04 was replaced with just 3, that will not work due to the change in format of filename
