I have a file with many lines which contain strings like [46ms] [986976ms] .. etc.
But with no rule regarding field separators or anything else.
I want to print ONLY THE STRING from each line , not the entire line !!!
For example from the lines :
I want to have the output :
Or even better only the numbers from each of these strings. I want it with awk because I need speed, I have very big files to work with.
Hi,
I know how to use awk to search some expressions like five consecutive numbers, , this is easy.
However, how do I make awk print the pattern that is been matched?
For example:
input: usa,canada99292,japan222,france59664,egypt223
output:99292,59664 (6 Replies)
Hi,

S. g. Ehr.
o. Jg.
v. d. Chijs
g. Ehr.
Now i would like to search for the strings and it also shall return the next column after the match.
awk -v FILE="search_strings.txt" 'BEGIN {... (10 Replies)
Hi AWK Experts,
Following is the data :

I want the output to be alligned with the pattern matching "BRH" inthe line.
The output should be look like:

With awk, how do I print the pattern matching line, then the subsequent lines following the pattern matching line. Varying number of lines following the pattern matching line. (9 Replies)
Hi experts , im new to Unix,AWK ,and im just not able to get this right.
I need to match for some patterns if it matches I need to print the next few words to it.. I have only three such conditions to match… But I need to print only those words that comes after satisfying the first condition..... (2 Replies)
Hi,

I have two files and desire to use the strings from $1 of file 1 (file1.txt) as search criteria to find matches in $2 of file 2 (file2.txt). If matches are found I want to output the entire line of file 2 (file2.txt) followed by fields $2-$11 of file 1 (file1.txt). I can find the matches, I cannot... (7 Replies)

sd_pid_get_owner_uid
SD_PID_GET_SESSION(3) sd_pid_get_session SD_PID_GET_SESSION(3)NAME
sd_pid_get_session, sd_pid_get_unit, sd_pid_get_owner_uid - Determine session, service or owner of a session of a specific PID
SYNOPSIS
#include <systemd/sd-login.h>
int sd_pid_get_session(pid_t pid, char** session);
int sd_pid_get_unit(pid_t pid, char** unit);
int sd_pid_get_owner_uid(pid_t pid, uid_t* uid);
DESCRIPTION
sd_pid_get_session() may be used to determine the login session identifier of a process identified by the specified process identifier. The
session identifier is a short string, suitable for usage in file system paths. Note that not all processes are part of a login session
(e.g. system service processes, user processes that are shared between multiple sessions of the same user, or kernel threads). For
processes not being part of a login session this function will fail. The returned string needs to be freed with the libc free(3) call after
use.
sd_pid_get_unit() may be used to determine the systemd unit (i.e. system service) identifier of a process identified by the specified
process identifier. The unit name is a short string, suitable for usage in file system paths. Note that not all processes are part of a
unit/service (e.g. user processes, or kernel threads). For processes not being part of a systemd unit/system service this function will
fail. The returned string needs to be freed with the libc free(3) call after use.
sd_pid_get_owner_uid() may be used to determine the Unix user identifier of the owner of the session of a process identified the specified
PID. Note that this function will succeed for user processes which are shared between multiple login sessions of the same user, where
sd_pid_get_session() will fail. For processes not being part of a login session and not being a shared process of a user this function will
fail.
If the pid paramater of any of these functions is passed as 0 the operation is executed for the calling process.
RETURN VALUE
On success these calls return 0 or a positive integer. On failure, these calls return a negative errno-style error code.
NOTES
The sd_pid_get_session(), sd_pid_get_pid(), and sd_pid_get_owner_uid() interfaces are available as shared library, which can be compiled
and linked to with the libsystemd-login pkg-config(1) file.
Note that the login session identifier as returned by sd_pid_get_session() is completely unrelated to the process session identifier as
returned by getsid(2).
