Deleting [CR][LF] using sed
Dear all,

I face a problem I can not solve: I have different lines in a file and some of them are ending with [CR][LF] ie "\r\n" and the others are ending with [LF] "\n".

My aim is to supress the string "\r\n" and concatenate that line with the following one.

For example:

Saying I have a file 4_test.csv with the 4 following lines:

Code:
[x004191a@xsnl11p370p tmp]$ cat -v 4_test.csv
123^M
456
789^M
0AB
[x004191a@xsnl11p370p tmp]$ od -c 4_test.csv
0000000   1   2   3  \r  \n   4   5   6  \n   7   8   9  \r  \n   0   A
0000020   B  \n
0000022
[x004191a@xsnl11p370p tmp]$

My aim is to get as a result a file with only the two following lines:

Code:
[x004191a@xsnl11p370p tmp]$ cat -v 4_test_target.csv
123456
7890AB
[x004191a@xsnl11p370p tmp]$ od -c 4_test_target.csv
0000000   1   2   3   4   5   6  \n   7   8   9   0   A   B  \n
0000016
[x004191a@xsnl11p370p tmp]$

I tried different syntax using sed but I was not able to suppress the two consecutive characters '\r\n' !

Any kind of idea would be greatly appreciated ... Thanks a lot,

Didier.

LEARN ABOUT DEBIAN

fixnt

fixnt(1)							      Debian								  fixnt(1)

NAME

       fixnt - Filter for the Windows NT postscript printer driver.

SYNOPSIS

       fixnt < BADFILE.ps > GOODFILE.ps

DESCRIPTION

       The  Windows  NT  postscript  driver has a tendency to make broken postscript files, that are incompatible with psutils.  fixnt is a filter
       that fixes these problems, allowing the use of psnup(1).

       The filter takes the broken postscript file on stdin, and outputs a fixed postscript file on stdout.  It has no other form  for	invocation
       and takes no options on the command-line.

OPTIONS

       fixnt  takes no options.

BUGS

       fixnt does not check for NTPSOct94.  For a workaround, use a sed(1) command to replace 'NTPSOct94' with 'NTPSOct95', like so:
	      sed 's/NTPSOct94/NTPSOct95/g'
       This is particularly important for Windows NT 3.5 users.

AUTHOR

       fixnt   was   written   by   Holger   Bauer   <Holger.Bauer@topmail.de>,  Michael  Rath	<rath@itsm.uni-stuttgart.de>,  and  Akim  Demaille
       <demaille@inf.enst.fr>.

REPORTING BUGS

       Report bugs to the Authors, but avoid sending large postscript files.

       Patches are always welcome; send to <bauer@itsm.uni-stuttgart.de>.
