Hi All,
Perhaps a dumb question, but how do you do a "print screen" within the X-Window in linux. I'm running KDE, is there a utility I can use in that package that I'm not aware of. Or, is there a way to turn on the <alt><print-screen> function with the keyboard?
Thanks in advance.

Hello everyone,
Following command sends word 'test' followed by an enter into a screen session (in our case screen_1). How do I print the result, if that would result ? How do I print the result, even if the program running in the session is locked ?
Thank you :)

Can anyone explain why I am having a alt print screen? I am used to alt print screen taking a picture of the top window in focus. Do I need to make a shortcut or something? (0 Replies)
Hi,
I've stored the output of a command into a variable.
The variable contains the following output:
outputline1 outputline2 outputline3 ...
How can I echo the variable so that the output is as follow and not one line:
outputline1
outputline2
outputline2
...
Thanks a lot! (4 Replies)

Hello,
I am on AIX.
When I encounter extended ascii characters and special characters on a file I need to print..
Byte position, actual character and line number.
Is there a simple command that can give me the above result ?
Thanks in advance (38 Replies)

systemd-veritysetup-generator
SYSTEMD-VERITYSETUP-GENERATOR(8) systemd-veritysetup-generator SYSTEMD-VERITYSETUP-GENERATOR(8)NAME
systemd-veritysetup-generator - Unit generator for integrity protected block devices
SYNOPSIS
/lib/systemd/system-generators/systemd-veritysetup-generator
DESCRIPTION
systemd-veritysetup-generator is a generator that translates kernel command line options configuring integrity protected block devices
(verity) into native systemd units early at boot and when configuration of the system manager is reloaded. This will create systemd-
veritysetup@.service(8) units as necessary.
Currently, only a single verity device may be se up with this generator, backing the root file system of the OS.
systemd-veritysetup-generator implements systemd.generator(7).
KERNEL COMMAND LINE
systemd-veritysetup-generator understands the following kernel command line parameters:
systemd.verity=, rd.systemd.verity=
Takes a boolean argument. Defaults to "yes". If "no", disables the generator entirely. rd.systemd.verity= is honored only by the
initial RAM disk (initrd) while systemd.verity= is honored by both the host system and the initrd.
roothash=
Takes a root hash value for the root file system. Expects a hash value formatted in hexadecimal characters, of the appropriate length
(i.e. most likely 256 bit/64 characters, or longer). If not specified via systemd.verity_root_data= and systemd.verity_root_hash=, the
hash and data devices to use are automatically derived from the specified hash value. Specifically, the data partition device is looked
for under a GPT partition UUID derived from the first 128bit of the root hash, the hash partition device is looked for under a GPT
partition UUID derived from the last 128bit of the root hash. Hence it is usually sufficient to specify the root hash to boot from an
integrity protected root file system, as device paths are automatically determined from it -- as long as the partition table is
properly set up.
systemd.verity_root_data=, systemd.verity_root_hash=
These two settings take block device paths as arguments, and may be use to explicitly configure the data partition and hash partition
to use for setting up the integrity protection for the root file system. If not specified, these paths are automatically derived from
the roothash= argument (see above).
