This is a single active line that generates the signature at the foot
of this message or rather it used to.

awk -F= '/PRETTY/ {print $2}' /etc/os-release | sed "s/\"//g", uname -r
cinnamon --version > /signature_line.txt

Since moving to a new machine and updating to Mint 21.3 it now generates this:

Comma should be semicolon?
Try tr -d '"' instead of sed?

You may be right but I found a solution before i could try it.
In case anyone wants to try it. Here is the full script:

#! /bin/bash
#
mint=$(awk -F= '/PRETTY/ {print $2}' /etc/os-release | sed "s/\"//g" )
# echo $mint
ktext="kernel version"
mversion=$(uname -r)
# echo $ktext $mversion
cmn=$(cinnamon --version)
echo $mint $ktext $mversion $cmn$'\n'AMD Ryzen 7 7700, Radeon RX 6600, 32GB DDR5, 1TB SSD, 2TB Barracuda > /home/alan/.config/sylpheed/sylpheed_signature.txt

Thanks, Alan

cinnamon --version I guess would replace the xfce4-about. Nice. Yes, a bit wordy !!👀

First the "awk -F= 'PRETTY {print $2}' etc/os-release " does not output anything. Even changing to
/etc/os-release fails.
Thus the sed has no option but to dump a help and about text to the screen.

I use this:
#!/bin/bash
echo `awk -F= '/PRETTY/ {print $2}' /etc/os-release | sed "s/\"//g"`" "`cinnamon --version`"
Al" > /home/alan/.thunderbird/Signature.txt

to do my sig. I run it just once a new OS comes along.
Does your script have the #!/bin/bash on line one?

Be aware that at least one editor, now has an "autocompletion" feature,
which completely destroys muscle memory, and is a giant fuckup. TURN THAT OFF.
That's how things like slashes and quotes are getting destroyed.

The command line version of field separator seems to work with these two formats.

awk -F=
awk -F"="

and in some cases, you need quotes so there's no mistake about
interpretation of potential backslash escaping.

The field separator could have been made into the double-quote character,
removing the double-quote which is not desired.

$ awk -F= '/PRETTY/ {print $2}' /etc/os-release

"Linux Mint 21.3"

$ awk -F"\"" '/PRETTY/ {print $2}' /etc/os-release

Linux Mint 21.3

Naturally, the thing relies on the specifics of the
format used today, so it's brittle towards changes.

*******

Inlining other bits and pieces, is a lot more ugly.

awk 'BEGIN { dummy = ("/usr/bin/uname -r" | getline) >0
str = sprintf(" Kernel version %s",$1)
dummy = ("/usr/bin/cinnamon --version" | getline) >0
str = str sprintf(" %s %s",$1,$2)
FS="\"" }
/PRETTY/ {print $2 str}' /etc/os-release

but at least that no longer uses SED.

If the program instead pulled the script inside a file, as in

$ awk -f some.awk /etc/os-release

then the field separator can be pulled inside the some.awk file.

BEGIN {
FS = "\""
}

I don't think it would eat F=" for example.

awk -F= '/PRETTY/ {print $2}' /etc/os-release | sed "s/\"//g", uname -r, cinnamon --version > signature_line.txt

Paste this into a terminal, to see the immediate output.

You can redirect this.

awk 'BEGIN { dummy = ("/usr/bin/uname -r" | getline) >0
str = sprintf(" Kernel version %s",$1)
dummy = ("/usr/bin/cinnamon --version" | getline) >0
str = str sprintf(" %s %s",$1,$2)
FS="\"" }
/PRETTY/ {print $2 str}' /etc/os-release

*******

Output should be:

Linux Mint 21.3 Kernel version 5.15.0-100-generic Cinnamon 6.0.4

That does not use SED.
