How, in general, can I do delimited searches in UNIX. i.e. How do I search for say the string "the" without finding there their other thesaurus...... AND including "the" at the beginning and end of a line eh? -- Pat Hertel Canadian Meteorological Centre Analyst/Programmer 2121 N.

I'm not quite sure what you mean with "in UNIX", but within vi at least, you can search for /\<the\> and you will find only stand-alone the's. Also \<the finds words beginning with the, etc. Guenter Steinbach gunter_steinbach@hplabs.hp.com

Search for three different strings, and then combine the results. The first string to look for is " the " (the in spaces), the next to look for is "%the" (sorry caret (begining of line character) doesn't exist on this VM machine), and the last to look for is "the$" (look for the at end of line). grep can be told to ignore case (-i) if this is what you are using. If vi or emacs, there should be a magic variable that can be set before doing the search. Gordon Haverland, U of Alberta SLOWPOKE Facility

From the shell, you can grep -w the. In vi or ex, you can search for \<the>\. These don't have to be used together- "\<the" would match thesaurus, "the\>" would match lathe. Now, the fun part. A really neat mapping to put in your .exrc is map ^R /\< map! ^R \>^M Since one of the mappings in in normal mode and the other is in insert mode, you can map both sequences to the same key. To search for the, you type ^Rthe^R. Easy on the fingers and on the memory. Dan Bloch dan@transarc.com

I just began getting comp.editors so I don't know if this has been noted yet, but in egrep (and other text processing utilities that understand egrep-style expressions) you can search for (^| )the( |$) You can replace the spaces with [ <tab>] (space followed by tab in brackets) if you want to include it as a delimiter.

I just began getting comp.editors so I don't know if this has been noted yet, but in egrep (and other text processing utilities that understand egrep-style expressions) you can search for (^| )the( |$) But not in VI. You can replace the spaces with [ <tab>] (space followed by tab in brackets) if you want to include it as a delimiter.

Just a small note: not all systems have a grep version that supports the \< and \> escapes. (vi nearly always does). In these versions of grep, there is usually a -w (or other) option which does the same thing. Altho that's not guaranteed everywhere, either. As with all things, your mileage may vary. -- asylvain@felix.UUCP (Alvin "the Chipmunk" Sylvain) ========================= Opinions are Mine, Typos belong to /usr/ucb/vi "We're sorry, but the reality you have dialed is no longer in service.
