see the below code -
Code:
#original File name
filename=tempblast12345A11093.out_

#define pattern 1
pat1=tempblast
#define pattern 2
pat2=11093.out_

#find the length of each pattern including filename
WLEN1=${#pat1}
WLEN2=${#pat2}
FLEN=${#filename}

#calculate the first position to cut
POS1=`expr $WLEN1 + 1`
#calculate the second position to cut
POS2=`expr $FLEN - $WLEN2`

#assign the new filename into new variable and print
NFILE=`echo $filename|cut -c$POS1-$POS2`
echo $NFILE

NAME
script - make record of a terminal session SYNOPSIS
script [-a] [filename] DESCRIPTION
The script utility makes a record of everything printed on your screen. The record is written to filename. If no file name is given, the record is saved in the file typescript. See WARNINGS. The script command forks and creates a sub-shell, according to the value of $SHELL, and records the text from this session. The script ends when the forked shell exits or when Control-d is typed. OPTIONS
The following option is supported: -a Appends the session record to filename, rather than overwriting it. NOTES
script places everything that appears on the screen in filename, including prompts. ATTRIBUTES
See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Availability |SUNWcsu | +-----------------------------+-----------------------------+ |CSI |Enabled | +-----------------------------+-----------------------------+ SEE ALSO
