[SOLVED] Search in a file

Hi!
I'm working on a radio script with several functions, but i need your help to continue.  I want to search for a spefic string in a file. The files content is like:

Super Hot Girls Radio Channel;http://lovepotion.org:666
Sir Camelot Danish Radio;kingandnight.org:231

So if i search for "io", this will appear:

Super Hot Girls Radio Channel
Sir Camelot Danish Radio

Re: [SOLVED] Search in a file

if i understood you, this is what you want:

grep "io" ./file.ext

Re: [SOLVED] Search in a file

You should tell your search function that io is the whole string, and no subset of whatever it finds. If not it will simply print all matches - not the exact ones but, as you can see, also the strings that contain your query and do not match it exactly.

Re: [SOLVED] Search in a file

simply,

awk -F ';' '/io/ {print $1}' ./file.txt

but, if in a script, and a variable is the search term you've got to switch the quoting like so

term="$1"
awk -F ';' "/$term/"'{print $1}' $file

term="$1"
awk -F ';' "/$term/"'{print $1}' $file

You should also declare "file"

yeah, i figured that was implied.  i just meant to highlight the fact that something like $term wouldn't get evaluated if you used the single quotes as in the first literal-search example.  thanks go to procyon for showing me that trick.

Re: [SOLVED] Search in a file

When using this:

awk -F ';' "/rad/"'{print $1}' $file

I get this output:

Mix Megapol
The Voice 105,9

But i don't want to search the whole line, just all text before the ";" char and the search should not be case sensitive.

Mix Megapol;mms://streaming.sbsradio.se/03872_MixMegapol_high
The Voice 105,9;mms://streaming.sbsradio.se/03872_TheVoice_high

Re: [SOLVED] Search in a file

You could do a grep, pipe it to sed to remove everything after the ";", and repeat the grep to make sure the match wasn't in the second half.

Re: [SOLVED] Search in a file

Try this:

cat file.txt | cut -d ';' -f1 | grep -i 'io'

This will print everything that contains 'io' before ';'

Re: [SOLVED] Search in a file

I'm no awk guru but this seems to work.

echo "Mix Megapol;mms://streaming.sbsradio.se/03872_MixMegapol_high
The Voice 105,9;mms://streaming.sbsradio.se/03872_TheVoice_high
The Rad;mms:/streaming.sbsradio.se/03872_The_rad" | awk 'BEGIN{OFS=FS=";";IGNORECASE=1}$1 ~ /rad/{print$1}'

The Rad;mms:/streaming.sbsradio.se/03872_The_rad" | awk 'BEGIN{OFS=FS=";";IGNORECASE=1}$1 ~ /rad/{print$1}'

this line seems to work best; throwing a second | grep "rad" on the end of mine would also ensure that the match is only for the first portion, but that's a bit of a hack.
