Hello everyone, my first post here, please feel free to inform me if my question can be better formatted so my future posts may be more clear.
I have a large text file which I need parsed in one specific way, I have done the rest of the processing, I am simply lacking the last aspect of such.
I need to look for lines in a file that begin with 'Key:' and of those lines that begin with key, delete all words in that line that do not contain the character '@', ignoring the first word (Key
So for example:
EDIT: Fixed example

I would prefer my solution be stream processing based (simply using an awk or sed command) instead of for-looping through the file, however I do not know if that is possible. I have explored possibilities with many tools but I am running out of ideas.
suppose u hava a file
G1354R tGGC-CGC
D1361N cGAC-AAC
I1424T ATC-ACC
R768W gCGG-TGG
Q1382R CAG-CGG
Q178E gCAG-GAG
Y181C TAC-TGC
.........cont.
So the question is
By searching for first word i.e.character say R
output shud be

Hi,
I have a single column of numbers from in tabulated text format ranging from 0 to 1. I want to manipulate the list of numbers so that if the number is greater than 0.5 (> 0.5), I get 1 - number. If the number is less than 0.5, the number is taken as it is and not altered. For example:

gsignal
PSIGNAL(9) BSD Kernel Developer's Manual PSIGNAL(9)NAME
psignal, pgsignal, gsignal, tdsignal -- post signal to a thread, process, or process group
SYNOPSIS
#include <sys/types.h>
#include <sys/signalvar.h>
void
psignal(struct proc *p, int signum);
void
pgsignal(struct pgrp *pgrp, int signum, int checkctty);
void
gsignal(int pgid, int signum);
void
tdsignal(struct thread *td, int signum);
DESCRIPTION
These functions post a signal to a thread or one or more processes. The argument signum common to all three functions should be in the range
[1-NSIG].
The psignal() function posts signal number signum to the process represented by the process structure p. With a few exceptions noted below,
the target process signal disposition is updated and is marked as runnable, so further handling of the signal is done in the context of the
target process after a context switch. Note that psignal() does not by itself cause a context switch to happen.
The target process is not marked as runnable in the following cases:
o The target process is sleeping uninterruptibly. The signal will be noticed when the process returns from the system call or trap.
o The target process is currently ignoring the signal.
o If a stop signal is sent to a sleeping process that takes the default action (see sigaction(2)), the process is stopped without
awakening it.
o SIGCONT restarts a stopped process (or puts them back to sleep) regardless of the signal action (e.g., blocked or ignored).
If the target process is being traced psignal() behaves as if the target process were taking the default action for signum. This allows the
tracing process to be notified of the signal.
The pgsignal() function posts signal number signum to each member of the process group described by pgrp. If checkctty is non-zero, the sig-
nal will be posted only to processes that have a controlling terminal. pgsignal() is implemented by walking along the process list headed by
the field pg_members of the process group structure pointed at by pgrp and calling psignal() as appropriate. If pgrp is NULL no action is
taken.
The gsignal() function posts signal number signum to each member of the process group identified by the group id pgid. gsignal() first finds
the group structure associated with pgid, then invokes pgsignal() with the argument checkctty set to zero. If pgid is zero no action is
taken.
The tdsignal() function posts signal number signum to the thread represented by the thread structure td.
