Fast and excludes words with apostrophes. For ubuntu, you can use wamerican or wbritish dictionaries, installable through aptitude.

Take a file and ,."()?!;: give a list of all the words in order of increasing length.

First of all use tr to map all alphabetic characters to lower case and also strip out any puntuation.

A-Z become a-z

,."()?!;: all become \n (newline)

I've ignored - (hyphen) and ' (apostrophe) because they occur in words.

Next use bash to print the length ${#w} and the word

Finally sort the list numerically (sort -n) and remove any duplicates (sort -u).

Note: sort -nu performs strangely on this list. It outputs one word per length.

Type the command. Then just use ssh command with tab to see all your ssh sessions.

You can also put it in your profile.

Thank you Nedzad !

Converts a single-track KML (Keyhole Markup Language) file to a GPX file. KML is the geospatial format of choice used by Google Earth, but doesn't interoperate with other GIS applications, websites, or devices ? almost all of which accept GPX.
