Destroy a shared memory segment

[g_p]

Good morning,

I want to destroy a shared memory segment and i would like to tell me how i can do it by typing it in a shell Unix type tcsh.

i use this command but it doen't work

ipcs -m | grep user_login_name | ruby -ne 'puts $_.split(" ")[1]' | xargs ipcrm -m

What do i do wrong?

Thanks, in advance

Well one of the things you did wrong was to post this post on the C board, since it has nothing to do with C, considering you just want some random command line crap to do it for you.

man ipcrm

Well ipcrm takes many arguments after it.

When i do

ipcs -m | grep user_login_name | ruby -ne 'puts $_.split(" ")[1]' | xargs ipcrm -m 12

12(is a shmid)

i get

usage: ipcrm [ [-q msqid] [-m shmid] [-s semid]
[-Q msgkey] [-M shmkey] [-S semkey] ... ]

What do i do wrong? Of course i have replaced the field user name with my user name but i dunno if i have placed the id of the shared memory in the correct field.

hence why I said to man ipcrm

ipcrm -m1 -m2 -m3

take a look at what that does. It should show you how to fix it

this really isn't the board for this as quzah said...so hopefully that helps you fix it, otherwise maybe a board specific to your OS would be better. Since I remember linux and solaris for example having different ipcrm

and really, if your doing what it looks like your trying, you probably shouldn't....who knows what program has set up a shared memory segment that your going to remove
