Hello tk:

Rather simple. You can do it with biterscripting ( http://www.biterscripting.com ) . Here is the small script to rename version.txt. (I have added comments so you can edit the script if necessary.)

# Go to directory where version.txt is stored.
ccd "some directory"     # Enter correct folder path here.

# Read version.txt into a variable.
var str content ; cat "version.txt" > $content

# Remove everything upto "GCA.atmID = ".
stex "^GCA.atmID = ^]" $content > null

# The next 8 characters are the new file name.
var str newname ; chex "8]" $content > $newname

# Rename file to $newname.txt.
system rename "version.txt" ($newname+".txt")

You are welcome.

If I understand the new task correctly, you have 255 .txt files, and you want to insert the name of the file as the first line of each file. That's also fairly simple with biterscripting ( http://www.biterscripting.com ) .

I will assume the .txt files are in C:\somefolder (and possibly subfolders). Here is the script.

#Script UpdateFiles.txt
var str list ; lf -rn "*.txt" "C:\somefolder"  > $list
while ($list <> "")
do
    # Get next file.
    var str file ; lex "1" $list > $file
echo -e "Processing file " $file
    # Get file contents into a string variable.
    var str content ; cat $file > $content
    # $file has full path. Get just the file name.
    var str filename ; stex -p "^/^l[" $file > $filename
    # Insert file name and "\n" before the first line.
    lin "1" ($filename+"\n") $content > null
    # Write updated content back to file
    echo $content > { echo $file }
done

script "C:\UpdateFiles.txt"

When using the following commands in biterscripting, they need to be preceeded by system.

copy
rename
move
delete


For example:

system copy "X.txt" "Y.txt"

system delete "X.txt"
