I am with MadeInGermany and others in trying to discourage use of csh/tcsh for scripting.
However, if you must use it, see the (old) references below. Search on Google, at publisher websites for possible PDFs, and at Amazon, the latter of which may have new copies of the books, but I'd try for a used copy there as well.

Is it possible to define the size of the array instead of directly giving the input?
Like x is the array variable and it has the size of 10. So that I could pass the input.
You could try this:
Code:
set ar=()
set x=10
foreach i ( `seq $x`)
set ar=($ar:q " ")
end
echo ${#ar}
However with my csh (tchs 6.22.01) using $arr:q to print array elements with quotes around them fails to print array elements that are blank. I had to append a single space instead.
Not quite sure what you mean by input as an array value. It's fairly straight forward to pre-load an array with fixed values or copy an existing array into another:
Code:
$ set ar=(10 165 22 156)
$ set ac=( $ar:q )
$ echo ${ar[3])
22
$ echo ${ac[4]}
156
I mean, the array size should automatically increase. ie., consider the array size as 5 initially, then if the input is in size of 10 data(1,2,3,4,5,6,7,8,9,10), then the array size should increase from 5 to 10.
This is the sample json I have pasted here. I want all the IP address strings to be converted into an array. For example "10.38.32.202" has to be converted to everywhere in the JSON. There are multiple IPs in a JSON I am pasting one sample object from the JSON. But the IPs already in an Array... (11 Replies)
