Question Have a sed file I'd like to extract fields from


Here's a sample from the file:

Code:
s/aborigone/native/
s/annoyed/vexed/
s/angry/furious/
s/anxious/nervous/
s/athletic/athlete/
s/cage/caged/
s/canoe/kayak/
s/capture/vidcap/
s/car,/automobile,/
s/carpark,/parking-lot,/
And what I want to do is extract the words in the second and third fields and write them to two text files so I have a "master" set of keywords and supplemental categories for annotating JPEG files.

This file is about three years old, and I've so far this year gone by finding the keywords I recall having a different Supp. Cat., but drawing these out to separate lists (I had them but things go missing or get deleted after two years) would prove a lot easier.

I'm sure it's a simple matter of using tr or awk or something along those lines, But like a lot of other things with scripting, I've forgotten the syntax of those tools.

I leave it to the board's magnanimity.

you can try:
awk -F/ '{print $2}'
for example
and read man page of awk if you have forgotten the syntax

Code:
cut -d/ -f2 < sourcefile > destfile1
cut -d/ -f3 < sourcefile > destfile2
-d delimiter to use, in this case, '/'
-f field to cut, the second and third, respectively

Smile Great suggestions, they both work well...

Moving on.

I used to have a script that read the items in field 2 (keywords), matched them with the items in field 3 (supplemental categories), dumped them to a temporary text file, sorted them alphabetically reading from that file, then wrote that string to another text file I could sed into the first file after adding ^ as a delimiter. Another script wrote each item in the strings into JPEG files using Exiftool. I still have the last script, and I'd like to rewrite the "match and sort" one if I could. It would make it much easier to annotate picture files like JPEGs whose metadata containers support "keys and cats," as I've always called them.

if you need help or want to discuss any of your scripts please post them (and also try to explain how does that work, what did you try to achieve, what kind of problems you have ...) - here, or in a new thread.

This doesn't help you with your extraction, but just for info it's aborigine, not aborigone.
