The code has worked impressively, many thanks for that.
I want to write a line to determine that, if the number of files with any prefix is more than 5, then print out the prefix names in one line (separated by a single space), such as
data_1 data_2
I wrote this line
However the output from this line is
It doesn't seem to recognise the single space I asked for between the prefix. Do you know what I may have done wrong?

Hi All,
I have some 6000 text files in a directory. My files are named like 1.txt, 2.txt 3.txt and so on until 6000.txt. I want to count the "number of words" in only first 3000 of them. Any suggestions?
I know wc -w can count the number of words in a text file. I am using Red Hat Linux. (3 Replies)
Hi!
In our current directory there are around 35000 files.
Out of these a few thousands(around 20000) start with, "testfiles9842323879838".
I want to count the number of files that have filenames starting with the above pattern. Please help me with the command i could use.

ppmtosixel(1) General Commands Manual ppmtosixel(1)NAME
ppmtosixel - convert a portable pixmap into DEC sixel format
SYNOPSIS
ppmtosixel [-raw] [-margin] [ppmfile]
DESCRIPTION
Reads a portable pixmap as input. Produces sixel commands (SIX) as output. The output is formatted for color printing, e.g. for a DEC
LJ250 color inkjet printer.
If RGB values from the PPM file do not have maxval=100, the RGB values are rescaled. A printer control header and a color assignment table
begin the SIX file. Image data is written in a compressed format by default. A printer control footer ends the image file.
OPTIONS -raw If specified, each pixel will be explicitly described in the image file. If -raw is not specified, output will default to com-
pressed format in which identical adjacent pixels are replaced by "repeat pixel" commands. A raw file is often an order of magni-
tude larger than a compressed file and prints much slower.
-margin
If -margin is not specified, the image will be start at the left margin (of the window, paper, or whatever). If -margin is speci-
fied, a 1.5 inch left margin will offset the image.
PRINTING
Generally, sixel files must reach the printer unfiltered. Use the lpr -x option or cat filename > /dev/tty0?.
BUGS
Upon rescaling, truncation of the least significant bits of RGB values may result in poor color conversion. If the original PPM maxval was
greater than 100, rescaling also reduces the image depth. While the actual RGB values from the ppm file are more or less retained, the
color palette of the LJ250 may not match the colors on your screen. This seems to be a printer limitation.
