dos to unix linefeeds

[matt]

I can't believe I don't know how to do this, but I don't know of an easy way to convert all of the files in a directory from dos linefeeds to unix ones. Surely there's a one-liner for this.

You have a several choices. There is a port called dos2unix or you can use commands listed in this site:

Hello,

There are two utilities for Unix systems that takes care of this issue. One is called unix2dos and the other is dos2unix. Some Unix systems include them in the base, some don't (but they are readily available on the internet if your system doesn't include them).

Hello,

Looks like 18Googol2 beat me to it!

I usually use Perl but you can count on sed and awk being in every BSD, perl, unix2dos, and dos2unix on the other hand not so much.

Alternatively, instead of just copy tje file, ftb, nfs, samba shoud take care of compatibility.

Here are one-liner functions I keep in my .shrc so I don't need to install dos2unix on each new machine:

dos2unix() { awk "{ sub(\"\r\$\", \"\"); print }" $1 > $2; }
unix2dos() { awk "sub(\"\$\", \"\r\")" $1 > $2; }

For a single file:

$ tr -d '\r' <file_with_CRLF >file_without_CR

To do this for all files in a directory is left as an exercise for the student

Thanks J65nko, I was just about to ask why no was was showing any love for tr. It's very handy.

And, here's one for some types of Apple textfiles which are also full of ^Ms but in a different way.

tr '\r' '\n' < testfile > testfile.new

Thats actually not perfect, it will leave in a few little things here and there--only ran into this once when a vendor sent us something, but it at least makes the file readable.

I just noticed that nvi doesn't handle dos line endings very well.
