[SOLVED] grep -o and strange character

di80 · 10-16-2012, 03:48 AM

hi,
i have googled around this but didn`t find any solution. I am trying to get some coordinates from a website using grep. Copied html source from a website to a txt file and i grep this file with

Code:

grep -o "(-?[0-9]{2,3}\.[0-9]+), -?([0-9]){2,3}\.([0-9])+" baltimore.txt

the result printed on terminal is as expected,well formed long/lat coordinates, but when i redirect output to a csv or txt file i get this

Code:

[01;31m[K39.29234400000	 -76.57470350000[m[K
[01;31m[K39.31975300000	 -76.61237900000[m[K
[01;31m[K39.31537620000	 -76.61709370000[m[K
[01;31m[K39.33807260000	 -76.60753880000[m[K
[01;31m[K39.35307750000	 -76.70132740000[m[K

the website is this

can anyone explain why do these characters come up and how can i get rid of them when i redirect output to a file?

my first thought is maybe a dos2unix issue. Try doing `dos2unix baltimore.txt` and then rerunning and see if that works.
The link you provided works, but brings up a default page so I don't know where you are getting the lat/log figures from to test myself.

hi thanks for the reply. I tried dos2unix but didnt change anything...
yes actually you need to select something from the dropdown menus, say "Time Frame" -> Past 30 Days and the "show results"...Then right click outside the map and select View source...there you can find the coordinates. i think they are in a js array.

Those look like ANSI colour codes, maybe you have grep set to highlight always? Try

Code:

grep --color=never -o "(-?[0-9]{2,3}\.[0-9]+), -?([0-9]){2,3}\.([0-9])+" baltimore.txt
