If you can switch to regular expressions (not shell pattern matching),
you could use AWK:
Code:
$ FILE_EXT='\\.sh$'                                                 
$ awk '$0 ~ pattern { print $9, $5 }' pattern="$FILE_EXT" files.txt 
sc1.sh 130
sc10.sh 10328
sc11.sh 9984
sc12.sh 9987
sc2.sh 3215
sc3.sh 3215
sc4.sh 2174
sc5.sh 2837
sc6.sh 5923
sc7.sh 5995
sc8.sh 6458
sc9.sh 8375

You should escape twice because the interpreter should scan the dynamic regular expression twice.

MAKEDEV(8)						      System Manager's Manual							MAKEDEV(8)

NAME
makedev - make system special files SYNOPSIS
/dev/MAKEDEV device... DESCRIPTION
MAKEDEV is a shell script normally used to install special files. It resides in the /dev directory, as this is the normal location of spe- cial files. Arguments to MAKEDEV are usually of the form device-name? where device-name is one of the supported devices listed in section 4 of the manual and ``?'' is a logical unit number (0-9). A few special arguments create assorted collections of devices and are listed below. std Create the standard devices for the system; e.g. /dev/console, /dev/tty. The VAX-11/780 console floppy device, /dev/floppy, and VAX-11/750 and VAX-11/730 console cassette device(s), /dev/tu?, are also created with this entry. local Create those devices specific to the local site. This request causes the shell file /dev/MAKEDEV.local to be executed. Site spe- cific commands, such as those used to setup dialup lines as ``ttyd?'' should be included in this file. Since all devices are created using mknod(8), this shell script is useful only to the super-user. DIAGNOSTICS
Either self-explanatory, or generated by one of the programs called from the script. Use ``sh -x MAKEDEV'' in case of trouble. SEE ALSO
