Reason: code tags, PLEASE!
To keep the forums high quality for all users, please take the time to format your posts correctly.
First of all, use Code Tags when you post any code or data samples so others can easily read your code. You can easily do this by highlighting your code and then clicking on the # in the editing menu. (You can also type code tags [code] and [/code] by hand.)
Second, avoid adding color or different fonts and font size to your posts. Selective use of color to highlight a single word or phrase can be useful at times, but using color, in general, makes the forums harder to read, especially bright colors like red.
Third, be careful when you cut-and-paste, edit any odd characters and make sure all links are working property.
you can 'grep -n' to get the line number of each $time_st and $time_en
you can use a combination of 'head' and 'tail' to output the subset of lines between $time_st and $time_en you want to search
you can use 'grep -c' to get the number of occurances of $word in that subset
Your greps need some escaping. Right now the . means 'match any character', not 'match .'
And your greps won't return anything because first you reject everything except your start time, and after that you reject everything except your end time. You need to match start and end and everything inbetween. Since grep doesn't understand what date and time means -- or what digits mean, for that matter -- I don't think grep can do what you want all by itself. There's several things with : in it that could match anyway, so that probably won't narrow it down to what you want. I'll work on this a bit...

Here's how you'd match exactly the hours you want.
Code:
#!/bin/sh
# Build a list of the hours we want, to fill into egrep
START=11
END=14
STR=$START
for ((N=START+1; N<=END; N++))
do
STR="$STR|$N"
done
# This will match 14:06 but not 10:02 since it starts at 11
echo -e "[22/Sep/2009:10:02:24 -0400]\n[22/Sep/2009:14:06:32 -0400]" |
egrep "/[0-9]+:($STR):"
You could tack another grep to match a specific hostname or what have you. It's not too sophisticated. You can't take it too much farther because grep can't understand what the dates actually mean.
This is about as complex as I'd bother making it in a shell script, since shell in general has a hard time processing date information. If you want something smart enough to just specify a beginning time and date and end time and date, I'd just use perl and process the dates wholesale to compare them.
start_time=10
end_time=14
word=cafe
# the number of the first line in the file with the start time and word
STARTLINE=grep -n ":$start_time:[0-5][0-9]:.*$word"|head -1|cut -f1 -d':'
# the number of the last line in the file with the end time and word
ENDLINE=grep -n ":$end_time:[0-5][0-9]:.*$word"|tail -1|cut -f1 -d':'
# the subset of lines between STARTLINE and ENDLINE
head -$ENDLINE file | tail -n +$STARTLINE > subsetfile
# the number of lines in subsetfile containing $word
grep -c $word subsetfile
Hello All,

Hi,
I would like to compare 2 files using awk, which I can do by using:
awk 'NR==FNR{a;next} (NR > 32 && $2 in a) {print $0}' File1 and File2.
If the name of the File1 is in another file (for example, column 4 in File 3) then how can I pass this column 4 to the awk command.
Thanks in... (1 Reply)
