Replace spaces with newlines

cat file.txt|perl -ne '$_=~s/\s+/\n/g; print $_;'
This command is useful for separating a text file where all the words are in one line. Any group of spaces will be replaced with a single newline. Instead of one long line of tokens. You'll have a long list of tokens. One token per line.

What Others Think

2 problems with that. 1. useless use of cat 2. use of perl how about: tr -s ' ' '\n' file.txt

Damn novas0x2a, that's why I hate man pages, you read stuff in there : --max-args=max-args -n max-args Use at most max-args arguments per command line. Fewer than max-args arguments will be used if the size (see the -s option) is exceeded, unless the -x option is given, in which case xargs will exit. and I still can't understand how it works.
