How to change file name using shell ?
Hi..

I have a list of input files as below:-
Code:
NXUPM.P999309.201002011144
NXUPM.P999409.201002011145
NXUPM.P999509.201002011146
NXUPM.P999609.201002011146
NXUPM.P999682.201002011201

I want to change it as below:-
Code:
NXUPM.P999309_999408
NXUPM.P999409_999508
NXUPM.P999509_999608
NXUPM.P999609_999681
NXUPM.P999682_999781

Actually, the output file naming conversion as below:-
Code:
NXUPM.<first sequence>_<last sequence>

The last sequence = first sequence + 99

Please help me

Thank you,
Baharin

Hensem I hope this works, i havent tested the code:

Code:
awk -F\. 'gsub("^[a-zA-Z]","",$2) {print $1".P"$2"_"($2)+99}' URFILE

Code:
ls -1 | awk -F"." '{
t1=substr($2,1,4);
t2=substr($2,5);
print "mv "$0 " "$1"."$2"_" t1 t2+99}'

if this gives what you want...you can run below...

Code:
ls -1 | awk -F"." '{
t1=substr($2,1,4);
t2=substr($2,5);
print "mv "$0 " "$1"."$2"_" t1 t2+99}' | sh

If you have rename command, then use this.
Code:
rename 's/(\d+)\.(\d+)$/$1 . "_" . ($1+99)/e' *

Code:
$ ls -l
total 0

You can also install the 'mmv' tool, which has convenient globbing-based file renaming features.
