Since the script I gave doesn't know what files will be passed in as arguments, thels PUR.*won't work in the general case. But, if you change:

Code:

awk 'BEGIN {
    fc = -1
}
FNR==1 {fc++
}

in the script I provided to:

Code:

ls -1 -- "$@"
awk 'BEGIN {
    fc = -1
}
FNR==1 {fc++
}

(Note that the first argument to ls (-1) uses the digit one; not the letter ell. It prints only the filenames in a single column, which is what you requested. With-l(the letter ell), you could get a long format listing of the files to be processed.
Using the-1(digit one) only matters when output from the script is not redirected to a file. This is the default when output is not directed to a terminal device file.)
or you could use:

Code:

awk 'BEGIN {
    fc = -1
}
FNR==1 {fc++
    printf("Processing file %d: %s\n", fc + 1, FILENAME)
}

to print the filename of each file as it is processed. And, if the output is not redirected to a file, it provides a progress report as processing starts for each file. Obviously, you can change the printf format string to format the display of the filenames in whatever manner you wish.
