sed and recognizing a runtime parameter
I thought I posted this before, but cannot see the post, so will re-post.
Apologies if it now appears twice !

My script prompts for a 7 digit parameter : read f1
I then run a find command to search for files with $f1 in its contents :
find . -print | grep $f1 {file} > temp1
I then run a cut to extract only the characters I want :
cut -c25-33,47-62 temp1 > temp2.
temp2 should no longer have $f1 in its contents, as it was in columns 18-24 prior to the cut.
However, if I look at temp2, I can see the contents of $f1 in columns 20-26.
This is because there is a date/time combination at the row end, & the format of jobno can fit .
Eg jobno 8100029
A row from temp2 : Z12345678ZZZ07012008100029

Is there a sed command that will allow me to delete these rows if I find pattern $f1 present ?

I tried export f1 and then sed “s/${f1}/d”
but got a garbled command message.

Many thanks !

rdma_post_recv

RDMA_POST_RECV(3)					   Librdmacm Programmer's Manual					 RDMA_POST_RECV(3)

NAME

       rdma_post_recv - post a work request to receive an incoming message.

SYNOPSIS

       #include <rdma/rdma_verbs.h>

       int rdma_post_recv (struct rdma_cm_id *id, void *context, void *addr, size_t length, struct ibv_mr *mr);

ARGUMENTS

       id	   A reference to a communication identifier where the message buffer will be posted.

       context	   User-defined context associated with the request.

       addr	   The address of the memory buffer to post.

       length	   The length of the memory buffer.

       mr	   A registered memory region associated with the posted buffer.

DESCRIPTION

       Posts a work request to the receive queue of the queue pair associated with the rdma_cm_id.  The posted buffer will be queued to receive an
       incoming message sent by the remote peer.

RETURN VALUE

       Returns 0 on success, or -1 on error.  If an error occurs, errno will be set to indicate the failure reason.

NOTES

       The user is responsible for ensuring that a receive buffer is posted and large enough to contain all sent data before the  peer	posts  the
       corresponding send message.  The message buffer must have been registered before being posted, with the mr parameter referencing the regis-
       tration.  The buffer must remain registered until the receive completes.

       Messages may be posted to an rdma_cm_id only after a queue pair has been associated with it.  A queue pair is bound to an rdma_cm_id  after
       calling rdma_create_ep or rdma_create_qp, if the rdma_cm_id is allocated using rdma_create_id.

       The  user-defined  context associated with the receive request will be returned to the user through the work completion wr_id, work request
       identifier, field.
