1. The actual reason why the output file test.txt is empty is because the URL contains some special symbols, such as "&", which breaks the issued command. This can be fixed with proper quoting:...

Try:
awk '....' Item="$targetItem" "$targetFile"

You also need to go back to single quotes (or do some more escaping) so you can use awk's interpretation of $0 instead of the shell's interpretation of $0. And, if a line could every be a string...

You can try this in awk:
awk '/measInfo/ || s {s=s?s"\n"$0:$0} /<\/measInfo>/{if (s ~ /string1/) print s; s=""}' file

It saves the xml block in a variable and prints it when the tag is closed...

Oops, I must've been sleeping when I wrote that!!!
Corrected and the required changes done in my earlier post.

With some sane input:
awk 'sub(/].*/,"")&&/^[0-9]/{print $0+0}' RS='[' file

as per your input..

this work fine. If not please provide some more variations from your input file..:)

awk -F "[][]" '{ for(i=2;i<=NF;i+=2){if($i ~ /^[0-9]/){print "["$i"]"}}}' file

Assuming your field separator equals " | " (space-pipe-space), try:
awk -F ' \\| ' '$2~/^10\.216\.22\.(XX|YY|ZZ)$/ && $4~/^[0-9]+$/' file

awk -F\| '$4~/[^0-9 ]/' file

awk -F\| '$4!~/^[0-9 ]+$/' input_file



JUST ANYTHING other than numbers....including special characters like $%^ etc

Try this one

awk -F\| '{if($4~/[a-zA-Z]+/){print}}' filename

awk 'NR>=998;NR==1000{exit}' file
sed -n '998,1000{;p;1000q;}' file

Try this:
awk -F"|" '$2 ~ "REQUEST" {s=$0;f=1;next} f && $2 ~ "RESPONSE" {print s RS $0;f=0}' file

I know, but the OP was happy with the previous solution that did just that and so I thought that is what he meant. Otherwise he could use this:
sed 's/[^:]*://' infile

sed 's/.*://' infile

you can use nawk , awk , gawk:


nawk -F":" '{print $NF}' infile > outfile

This is the culprit. The "eval" sends the line through the evaluation process a second time, but the first time it has already eaten away your quotation and this second time the newline terminates...

egrep '"GET .*\.gif' apache.log

Can't you escape the "-" before executing "grep"?

Check below:

$ text="-8x7YTVNk2KiuY-PWG5zzzjB-zzw"
$ string="-8x7YTVNk2KiuY-PWG5zzzjB-zzw"
$ echo "${text}" | sed 's/^-/\\-/g'...

where is your echo statement ?

can you post the $string and $text values ?
