Hello,
W/in the script I'm working on, I have a need to take a column from a file, and format it so I can have a variable that will egrep for & invert the regex from another file.
My solution is this:
VAR=`awk -F, '{print $2}' $FAIL | sed 's/-i/\|/g'`
VAR2=`echo $VAR | sed 's/... (5 Replies)
Open to a sed/awk/or perl alternative so that i can stick command into my bash script.
This is a problem I resolve using a combination of cut commands - but that is getting convoluted. So would really appreciate it if someone could provide a better solution which basically replaces all... (3 Replies)

ns_thread
ns_thread(3aolserver) AOLserver Built-In Commands ns_thread(3aolserver)__________________________________________________________________________________________________________________________________________________NAME
ns_thread - commands
SYNOPSIS
ns_thread begin script
ns_thread begindetached script
ns_thread get
ns_thread getid
ns_thread wait tid
ns_thread yield
_________________________________________________________________DESCRIPTION
ns_thread begin:
begins a new thread which evaluates the specified script and then exits. It returns a thread ID that must eventually be passed to
ns_thread wait. (Failing to call ns_thread wait will eventually result in no new threads being created.)
ns_thread begindetached:
begins a detached thread that doesn't have to be (and can't be) waited for.
ns_thread get:
gets the thread ID of the current thread. The result is a thread ID that can be passed to ns_thread wait and may look something like
"tid532".
ns_thread getid:
gets the thread integer number for the current thread. The result is a small integer used for identifying threads is a human-read-
able way, such as "1" or "1120", for example.
ns_thread wait:
waits for the specified thread to exit. The tid argument is a thread ID returned by ns_thread begin or ns_thread get.
ns_thread yield:
causes the current thread to yield.
EXAMPLES
This example is similar to the example under the ns_sockselect function of connecting to the 10 servers and waiting to service them with
the ns_sockselect command. In this case, though, each connection gets it's own thread.
# This is the procedure which is evaluated for each thread and # handles a single connection to host number $i
proc getpage {i} {
global pages
# new thread will start here - first connect to host
set host [format "www%2d.foo.com" $i]
set fds [ns_sockopen $host 80
set r [lindex $fds 0]
set w [lindex $fds 1]
# next, send request 0r"
puts $w "GET /index.htm HTTP/1.0
flush $w
# then read page
set pages($i) [read $r]
# and close sockets
close $w
close $r
# thread goes away here and other threads waiting
# on ns_thread wait will wakeup }
# Here's the loop which creates the threads which run getpage. for {set i 1} {$i < 9} {incr i} {
set tids($i) [ns_thread begin "getpage $i"] }
# wait for the threads to exit and then process the pages for {set i 1} {$i < 9} {incr i} {
ns_thread wait $tids($i)
# output page
... process the page in $pages($i) put there by other thread ... }
Note that the code here is much simpler to follow than the ns_sockselect example; that's the benefit of multithreaded programming. However,
it uses more resources as threads need to be created and initialized. This can be a problem if you plan to create many threads.
