Hi, I thought about it, and even though I may do it the hard way, I think it gets the job done... and to be on the safe side, make working copies, this one moves the wanted files into their own directory.
I tried it and it works on my machine
Code:
#!/bin/bash
#Assuming Your current working directory is ok to work in and the files
#are located in the directory verfiles (create working copies there)
#First sort, if the naming is consistent, that should be a good start
ls -1 verfiles | sort > verfiles.srt
#split the filenames on each "firstname" so they will have their own file
prefix=""
while read filename; do
#Determine the "prefix"
curprefix=$(expr match "$filename" '\(^[a-Z]*_\)')
#Has it been read before?
if [ x$curprefix != x$prefix ] ; then
#We have a new "firstname"
prefix=$curprefix
fi
echo $filename >> $prefix.lst
done < verfiles.srt
#cleanup
rm verfiles.srt
#Where to keep the "last two" of each...
mkdir saved-verfiles
#Now for each .lst file, manipulate it a little for easier numerical sorting
for x in *.lst; do
#And this next bit is VERY lazy of me, but as I said,
#I ASSUME that the naming is consistent ;)
myarr=($(tr V " " < $x | tr . " " |sort -n -k2 | tail -2))
mv verfiles/${myarr[0]}V${myarr[1]}.${myarr[2]} saved-verfiles
mv verfiles/${myarr[3]}V${myarr[4]}.${myarr[5]} saved-verfiles
done
Hi,
I use a Windows-based program called <a href="http://www.coast.com">Coast Webmaster</a> for moving large numbers of HTML files in one directory to another directory. As you drag and drop each file or entire directory of files to new locations in the web root directory tree, this utility... (1 Reply)

Hi all ---
I have the need to manage multiple versions of a set of utility scripts -- both shell and SQL and other .dat files. I am wondering if anyone out there knows of a good way to "PATH" to SQL and text files in a way similar to how PATH facilitates finding executables in a pre-specified... (2 Replies)
Hi all,

So, I have a machine running solaris (x86) and it has two different versions of Math::BigInt installed on it. The older version is 1.77. The newer version is 1.87 (via activeperl). When I run my code, one of the modules I use needs at least version 1.78. Somehow, it defaults to looking at the... (5 Replies)
In a nutshell, I want $USER to reflect my user ID in a script run with sudo. I'm working with OSX in case that makes a difference.
If I 'sudo echo $USER', I get my user ID. But if I 'sudo myscript.sh' and myscript.sh has a line to echo $USER, I get 'root' I'm hoping there's a switch I can add... (1 Reply)
