Operating Systems AIX Pattern to replace ^M and ^Y in a 4.2 AIX text file Post 302316791 by TonyFullerMalv on Saturday 16th of May 2009 04:16:54 PM

What you could really do with is dos2unix(1) that comes with Solaris and Linux but not with AIX IIRC, so instead you can use sed:

dos2unix:
Code:
sed -i 's/\r//' file

unix2dos:
Code:
sed -i 's/\n/\n\r/' file

from: UNIX BASH scripting: Linux flip command - alternative of dos2unix,unix2dos

or

dos2unix:
Code:
$ sed 's/^M$//'  input.txt > output.txt

unix2dos:
Code:
$ sed 's/$'"/`echo \\\r`/"   input.txt > output.txt

from: Howto: UNIX or Linux convert DOS newlines CR-LF to Unix/Linux format

The dos2unix examples will get rid of the carriage returns for you I will leave a scripting guru to work out the removal of particular unwanted line feeds.

NAME
dos2unix - mtools utility to convert a DOS file to UNIX SYNOPSIS
dos2unix msdosfile OPTIONS

Name of the file to convert. DESCRIPTION
The dos2unix command converts a file from DOS format to UNIX format. The converted file replaces the original file. Subdirectory names that contain the '/' or '' separator are supported. If you use the '' separator or wildcards, you must enclose file names in quotes to protect them from the shell. The mcd command can be used to establish the device and the current working directory (relative to DOS), otherwise the default is A:. EXIT STATUS
The following exit values are returned: Success. Failure. ENVIRONMENT VARIABLES
The following environment variables affect the execution of dos2unix: If set, this variable names the file that contains the name of the current mtools working directory as established by the mcd command. If this variable is not set, the file $HOME/.mcwd is used. FILES
Contains the name of the current mtools working directory as established by the mcd command. If this file does not exist, the default mtools working directory is A:. Executable file SEE ALSO
