How can I read the specific position data in a file


Hello All,

Can you help me in writing a script for reading the specific position data in a file and if that data found in that file that particular file should be renamed.

Ex: Folder : C:\\test
and Filename : CLSACK_112214.txt,CLSACK_112314.txt,CLSACK_112414.txt
Contents in the file would be :
ISA* * * ~GS*CLS02*4010~ -> CLSACK_112214.txt
ISA* * * ~GS*CLS01*4010~ -> CLSACK_112314.txt
ISA* * * ~GS*CLS00*4010~ -> CLSACK_112414.txt

So first I need to read the first file CLSACK_112214.txt and in that I need to check conditions like

if the position from 15 to 21 == "*CLS02*"
then rename the current file(CLSACK_112214.txt) to UPDATEACK_112214.txt

Else if the position from 15 to 21 == "*CLS01*"
then rename the current file(CLSACK_112314.txt) to UPDATEACK_112314.txt

if the position from 15 to 21 == "*CLS01*"
then rename the current file(CLSACK_112414.txt) to UPDATEACK_112414.txt

So the script should read the files in the folder one by one and if any of the 3 conditions below gets satisfied then the current file should be reanme from CLSACK_XXXXXX.txt to UPDATEACK_112414.txt and then it should read next file and another file until the files in the folders scanning gets completed.

So anyone can give a script for the above scenario , it should be really help ful.

Thanks
Nandu

this: "C:\\test"
does not look like linux.

in what language do you want to script? bash?
there's a really good bash tutorial/wiki website here:http://mywiki.wooledge.org/
once you come up with something, show us what you tried, we might be able to assist.but we are not going to write that script for you.
