I need to process a file line-by-line using some value from a shell variable
Something like:
I can't make the '-s' work in the '-p' or '-n' input loop (or couldn't find a syntaxis.)
I have searched and found https://www.unix.com/302343759-post2.html, but it doesn't work
Is it possible (without havy sysntaxis, as ENV(..), for exmpl.) in the input loop?
What is the difference between defining the global variable through our and using use vars ?
Is the variable created using our goes beyond even package scope?
Thanks in Advance !!! (3 Replies)

bench(1) General Commands Manual bench(1)NAME
bench - http benchmark
SYNOPSIS
bench [-n requests] [-c concurrency] [-t timeout] [-k] [-K count]
[-C cookie-file] [http://]host[:port]/uri
DESCRIPTION
bench is a HTTP benchmark program that can fetch the same URL over and over again, or fetch several URLs (coming in from stdin).
If you specify a URL on the command line, this URL will be fetch many times (specify with -n, default: 10000) with several connections open
in parallen (specify with -c, default: 10).
You can specify a timeout (per request) in seconds with -t.
The -k switch activates keep-alive mode. In keep-alive mode, the TCP connection is not closed between requests. You also have to specify
how many HTTP requests can go over one TCP connection with -K.
bench can also send one HTTP cookie per connection, as specified using a cookie file. The cookie file is read line by line, and each
request gets the next line inserted into it. So each line should look something like this:
Cookie: foo=bar
If the end of the file is reached, bench restarts it at the beginning.
