[Solved] Stripping ret of the lines in a file (sed question)
Hi all,

I didn't use SED for 20 years and was never an expert. So my current knowledge is about zero. Please be patient with me. I'm neither a native speaker.

I have a huge dictionary file and want the rest of the lines stripped. Everything after (and including) the "/" should be stripped. I just want to obtain the "pure" words.

example (see attached file):

Code:
emanate/XSDVNG
emanation/M
emancipate/DSXGN
emancipation/M
emancipator/MS
Emanuele/M
Emanuel/M
emasculate/GNDSX
emasculation/M
embalmer/M
embalm/ZGRDS
embank/GLDS
embankment/MS
embarcadero
embargoes
embargo/GMD
embark/ADESG
embarkation/EMS

Please note, that not every line has a "/" in it. For example "embarcadero" has not. No action should be taken then.

Can someone give me the best command to do the job? Your help is very much appreciated.

NAME

       an - Anagram generator

SYNOPSIS

       an  [-w]  [-c  string]  [-d  dictionary] [-l number_words] [-m word_length] [-u string] [-n number_anagrams] [-h] [-v] [--words] [--contain
       string] [--dict dictionary] [--length number_words] [--minimum word_length]  [--used string] [--number  number_anagrams]  [--help]  [--ver-
       sion] PHRASE

DESCRIPTION

       an  finds  all  anagrams  which	can  be  made  from  the letters in PHRASE, using words in the specified dictionary. The default is to use
       /usr/share/dict/words.

       -w, --words
	      Print words that the letters in PHRASE can make, then exit.
