TR or SED command to add carriage return at the end of line feed

[rsasha]

Hi all!

I have a bit of trouble with printing and wander how can I use TR or SED command to add carriage return at the end of line feed. I need to set this up as a pre-processing filter for all remote printers.

TIA.

The sed command is a very useful command for filtering text files.
It can also be incorporated into the virtual printer as a filter
using the following method.

Setup:

Create a sed filter file that does what you want. In the first case
I have created one to remove all carriage returns from a file. I
call this file /usr/local/rmcr

vi /usr/local/rmcr and add
s/^M//g


Next modify the virtual printer using lsvirprt.

lsvirprt
Select the virtual printer to add the filter
Change the f attribute to point at the filter. This is done by
assigning f a single character that points at an attribute with
the file name

f=l

Now change the fl attribute to use the filter file that was
created earlier. I like to use fl~v to use a vi interface to
edit the attribute. Inside the vi session enter the following:

Command String for the "l" Filter.
fl = /usr/bin/sed -f /home/labs/aixtra/sed.ch

'/usr/bin/sed -f /usr/local/rmcr'

save and exit the vi session and exit lsvirprt.

Now print to the queue and the files should have cr removed, etc.

I believe the question was how to add the carriage return:

cat input_file | sed 's/$/^M/' > output_file

You could also try changing the settings of your remote printer(s) so that on receipt of a LF it prints a CRLF.

Most printers support this setting.

The setting will be something like LF=CRLF.

If you are using a PCL printer, then change the virtual printer attribute to
ct=%&k2G
This will tell the printer to add the cr to lf.
