Doesn't really make much sense to say which is closer, however you could at least say that the default gateway of 10.0.0.1 is out through eth1 on the 10.0.0.0/24 network.

Your host knows where...

What the example says is this:

If you want to send to a system in the 10.0.0.0 network, you don't have to use a gateway (router). Just send the packet out of the eth1 interface and the destination...

That is because you printf "SP" without a comma. In fact, it's the ${morse["I"]} following the space in input.

Thats a fun excercise :D

Here is my test to reverse the input as well:
I mean, it has to be able to translate it both ways, doesnt it? ;)

Just add a newline character to the printf command
printf "%s\n" SPDon't forget to do the same for the other printf command between else and fi.
The third printf does not need to be modified.
...

Potential improvement:
N=${input:$i:1}

if [ "$N" = " " ]; then
printf "%s" SP
else
printf "%s" "${morse[$N]}"
fi
done

printf "%s\n" EOT

Declare the array BEFORE you execute the loop.

And, don't use the same name for a scalar variable and an array variable.

Is this the idea?
I put the loop at the end so bash will see the array
as it reads top down. I think that's right...
I'm not sure I got the associative array part right though? echo...

[ and ] must have a spaces before and after them

Try this code (note it needs to be "hardened", e.g. checking if $1 and $2 were supplied, is $1 less than $2, etc.):
#!/bin/bash

ARGSTART=$1
ARGSTOP=$2

COUNT=0

while IFS= read -r line; do

Don uses string substitution feature of bash, you can man bash and read all the details

To demonstrate:



$ a="123 abc # qwe"
$ echo ${a#*#}
qwe

$ a="123 abc + qwe"
$ echo...

Don't tell us it "prompts me for more info"; show us the exact message that bash prints as a prompt.

When I save the following:
#!/bin/bash
found=0
n=1
while read -r line
do # Look for...

Hello ksmarine1980,

Following may help you in same if we need to print line number along with line's content.

Hello ksmarine1980,

Not sure if I am correct, but I have given a while loop solution also in my previous post. Could you please let me know if that helps or you need anything else here.

...

In command arguments have variables in quotes!
echo "$line"
echo "$i $line"
Other suggestions:
printf "%05d %s\n" $i "$line"
read -r ...

For the purposes of this exercise, how do you define "comment"?

A basic outline of what you want is something like:
#!/bin/bash
n=1
while read -r line
do if [ comment_present ]
...

That last statement looks over-complicated to me I think:

if ( $2 == "string" ) then
...
else if ( $2 == "other" ) then
...
else
echo "operator is invalid or missing"
endif

But...

I told you both ways. CSH is not UNIX, it's a nonstandard language which was popular in the early 80's(it supported "fancy" things like line editing!) but has only clung to a weird, tenuous life...

I generally refuse to use csh and its derivatives for reasons already mentioned in this thread... But, I think you want to change:
else if ( $2 =~ "times" ) then
@ c = $1 * $3
...

Be sure to test it with the same number duplicated several times.

{
for (i=1; i<=NF; i++) {
if($i=="0" || $i+0 != 0) {
array[$i+0]++
if ($i+0 > max)...

Populating A[] and calculate count and average:

{
$1=$1
for (i=1; i<=NF; i++) {
if($i=="0" || $i+0 != 0) {
A[++count]=$i+0
tot+=$i+0
if ($i+0 > max) max=$i+0...

Try this:

{
gsub(/[^[:space:]]*[^[:digit:][:space:]][^[:space:]]*/,x,$0)
$1=$1
for (i=1; i<=NF; i++) {
if ($i > max) max=$i
if($i < min || !min) min=$i
}
}
END{
...

This will clean out all non-digits (you need the . character for decimal numbers)

tr -d '[:alpha:]' < infile > newfile
