Not sure what sar is, but this example uses cat to display a text file.
I know that works, you can man sar to see what it does and I know it
writes to stdout as per my test.
This is what the output shoudl look like its just plain text, I have no clue
why this is an issue. I even wrote a 3 line program that does a printf to stdout and piped it to sed and that worked. What's the mystery?
I have searched the forum for this - forgive me if I missed a previous post.
I have the following file:
blah blah blah
blah blah blah

Hi
I am having some issue editing a file in sed.
What I want to do is, in a loop pass a variable to a sed command. Sed should then search a file for a line that matches that variable, then remove all lines below until it reaches a line starting with a constant.

systemd-cat
SYSTEMD-CAT(1) systemd-cat SYSTEMD-CAT(1)NAME
systemd-cat - Connect a pipeline or program's output with the journal
SYNOPSIS
systemd-cat [OPTIONS...] [COMMAND] [ARGUMENTS...]
systemd-cat [OPTIONS...]
DESCRIPTION
systemd-cat may be used to connect the standard input and output of a process to the journal, or as a filter tool in a shell pipeline to
pass the output the previous pipeline element generates to the journal.
If no parameter is passed, systemd-cat will write everything it reads from standard input (stdin) to the journal.
If parameters are passed, they are executed as command line with standard output (stdout) and standard error output (stderr) connected to
the journal, so that all it writes is stored in the journal.
OPTIONS
The following options are understood:
-h, --help
Print a short help text and exit.
--version
Print a short version string and exit.
-t, --identifier=
Specify a short string that is used to identify the logging tool. If not specified, no identification string is written to the journal.
-p, --priority=
Specify the default priority level for the logged messages. Pass one of "emerg", "alert", "crit", "err", "warning", "notice", "info",
"debug", or a value between 0 and 7 (corresponding to the same named levels). These priority values are the same as defined by
syslog(3). Defaults to "info". Note that this simply controls the default, individual lines may be logged with different levels if they
are prefixed accordingly. For details, see --level-prefix= below.
--level-prefix=
Controls whether lines read are parsed for syslog priority level prefixes. If enabled (the default), a line prefixed with a priority
prefix such as "<5>" is logged at priority 5 ("notice"), and similar for the other priority levels. Takes a boolean argument.
EXIT STATUS
On success, 0 is returned, a non-zero failure code otherwise.
EXAMPLES
Example 1. Invoke a program
This calls /bin/ls with standard output and error connected to the journal:
# systemd-cat ls
Example 2. Usage in a shell pipeline
This builds a shell pipeline also invoking /bin/ls and writes the output it generates to the journal:
# ls | systemd-cat
Even though the two examples have very similar effects the first is preferable since only one process is running at a time, and both stdout
and stderr are captured while in the second example, only stdout is captured.
