A sed version...


sed -n 's/^.*<\(CountryCode\|CountryName\|RegionName\|City\)>\([^<]*\)<\/.*$/\2/p


js.

You could use a case statement:


case $REMOTE_USER in
joe|bob|elvis) echo ok ;;
*) echo fail ;;
esac


js.

You want to create "array like variables" in bourne shell? Hm. How about this?


n=0
for val in a b c
do
eval var$n="$val"
n="`expr $n + 1`"
done


That would give you 3...

That assumes there are no fields starting with blanks, that are one or more spaces, etc. I'm thinking the OP wants to remove commas from quoted fields, so this might be safer:

sed...

echo $* | tr -d ' '

Here's another in bash (not bourne):

var="$*"
echo ${var// /}


js.

In what language?

Assuming bourne shell, how about:


expr index filename len >/dev/null && echo ok


js.

True. I tend to type one-offs on a single line... Tsdk, tsk. :-)



Depends on the shell you use...

js.

grep '[013-7]'

js.

for d in dir/* do; [ -d "$d" ] && egrep -v "^`basename $d`$" file.txt > /tmp/file.$$ && mv /tmp/file.$$ file.txt || exit 1; done

js.

You could try adding a -regex or -name to find, making sure the filenames returned by find are in an acceptable format, or add a grep right before your awk.

js.

Are you talking about "snmptrap"? You could probably do something like:

while read line; do snmptrap {args here} "$line"; done < input.txt

js.

I don't think sed supports the {##} suffix, but perl does. Here's an (untested) adaptation of the above:

perl -n -e 's/^(.{180})([^-]*)-(.*)$/$1-$2$3/' input.txt

js.

if echo 123 | grep -q 2; then echo ok; fi

Depending on how you're using wget, you can use the routing table to send traffic through the right interface (assuming different destinations for those wgets).

I have a little problem. To keep a configuration simple, I've exceeded my perl knowledge. :-) I've worked with multi-dimentional arrays before, but this one has me beat:


@info = (
{
