Those of us doomed to work in both the Unix and Windows world have many times encountered files that were create/editted on systems other that the one we are on at the time of our edits. The symptom of this is the dreaded '^M' at the end of our Unix lines as seen in the example file file.dos:
line1^M line2^M ^M
This tool changes <CR><LF> (DOS) to just <LF> (UNIX).
Most UNIX installations have a similar tool but this one optionally replaces the input file with the converted file.
usage() {
cat<<-EOF
dos2unix [FLAGs] FILE
Convert from DOS to UNIX files
Flags:
-h print this help text
-l copyright notice
-r replace the input file with the new file
-x run a demo
EOF
exit
}
First, if you have installed anything from this site before, save your config file to somewhere safe.
Second, copy the following files to your directory (from
either ~timm/public_html/dm or
http://www.cs.pdx.edu/~timm/dm or
from http://www.cs.pdx.edu/~timm/dm/dos2unix.zip):
Third, make dos2unix executable:
chmod +x dos2unix
Fourth, compare your safe version of config
with the new version you just copied and fix up any paths.
Five, edit this file and config.
The first line of this file should point to your local bash shell.
and you'll need to check at least the #paths section in config
Defaults:
replace0=0
Paths:
. config
demoDos2Unix() {
cp file.dos file1.dos
cp file.dos file2.dos
replace=0
main file1.dos > file1.unix
replace=1
main file2.dos
cat<<-EOF
Now call vi file.dos file1.unix file2.dos
file.dos SHOULD contain ^M (this is the file we started with)
file1.unix SHOULD NOT
file2.dos SHOULD NOT
EOF
