Older Banner® upgrades used edread to extract the files, however this program is only available on DOS systems, while most upgrades needed to be done on Unix Environments. This meant Banner® admins needed to extract files on a Dos box, then needed to ftp the files over the a unix system before actually applying each upgrade.
The problem here is that Unix and Dos use different values to represent the carriage character. Dos carriage returns show up as ^M in Unix.
The following script fixes this problem.
#!/bin/ksh
#
# begin dos2unix
#
# Usage: dos2unix [file]
cat $1 | tr -d "\015" > .tmp
mv .tmp $1
#
# end dos2unix
