need to replace spaces with comma (ascii file)

ferradura · 02-02-2007, 02:51 PM

i have a 40 MB ascii file, with millions of numerical characters.
i needed to change it`s format,replacing the spaces in it with a ; or , or even |
Ex.:

3.36700000 -0.29860000 3.13370000 179 179 179
to
3.36700000;-0.29860000;3.13370000;179;179;179

Does any one know a simple script to speed up the process? Something in bash would do it...

Thanks

This doesn't take international characters or multiple spaces, etc. into account:

Code:

$ sed 's/ /;/g' test.log > testnew.log
$ cat test.log
3.36700000 -0.29860000 3.13370000 179 179 179
$ cat testnew.log
3.36700000;-0.29860000;3.13370000;179;179;179
