Hi all,
I have a file that contains many lines, but only a few are of my interest, so I'm cutting it with grep + awk, and the result I get is for example
Code:
line 0
line 1
line 2
line 3
line n
Now I want to store each line in an array "cell" so I can use it later calling to
${array[0]}, ${array[1]}, etc.
When I tried it doing
Code:
array[$count]=$(grep line file.txt | awk -F \" '{print $2}')
and then
Code:
echo ${array[@]}
it gives me
Code:
line 0 line 1 line 3 line n
but doing
Code:
echo ${#array[@]
shows that all I have is a single component, so I can't use each value
What am I doing wrong?
Thanks in advance
great, it works, thanks!
But I find it very slow and time consuming, perhaps I need to explain more deeply what kind of data I'm using.
It's a very long xml file with several fields, I'd post here a short exerpt and then explain what I'm planning to do.
I've omitted a lot of irrelevant lines and stuff I don't need, now, I have some 14000 entries with the same tags, as in "Customer1" and "Customer2", up to "Customer14000"!!, so I thought if I save every "csRouteAlias" value in its array, and then every "csRouteIpAddr" values in another array, and so on, I can be able to "re-ensemble" the xml the way I want, using ${csRouteAlias[24] and ${csRouteIpAddr[24]} would give me a matched value according to the original XML, am I right?
Now, how can I do it and perhaps there is a better way?
TIA
I have the following code and for some reason when I call the program using
/home/tcdata/tatsh/trunk/hstmy/bin/bash/raytrac.bash --cmod=jcdint.cmod
I get
hasArgument =
hasArgument = true
Somehow the array element is returning even though I have not chosen the option.

Hi,
I am writing a bash shell script. I would like to execute a statement only if an array contains a specific value. For example:
