Question

Why use the AWK, which, BTW, is a terrific language? It does have some overhead/startup costs. I just pegged myself as a 300Mhz P3 user, didn't I? Smilie
Code:
$ ls -l *.root
-rw-rw-r-- 1 mhofer mhofer 0 Jul 30 07:42 L1File1_000_981.root
-rw-rw-r-- 1 mhofer mhofer 0 Jul 30 07:42 L1File2_000_980.root

$ ls *.root | tr "\n" ' ' > OutPutFile

$ cat OutPutFile
L1File1_000_981.root L1File2_000_980.root

I'm pretty sure something could be done with sed on the output of ls *.root as well,

[later] Of course

Code:
$ ls -x *.root > OutPutFile

$ cat OutPutFile 
L1File1_000_981.root  L1File2_000_980.root

works as well but note the extra separating space. SmilieSmilie

SYSTEMD-VOLATILE-ROOT.SERVICE(8)                           systemd-volatile-root.service                          SYSTEMD-VOLATILE-ROOT.SERVICE(8)

NAME
systemd-volatile-root.service, systemd-volatile-root - Make the root file system volatile SYNOPSIS
systemd-volatile-root.service /lib/systemd/systemd-volatile-root DESCRIPTION
systemd-volatile-root.service is a service that replaces the root directory with a volatile memory file system ("tmpfs"), mounting the original (non-volatile) /usr inside it read-only. This way, vendor data from /usr is available as usual, but all configuration data in /etc, all state data in /var and all other resources stored directly under the root directory are reset on boot and lost at shutdown, enabling fully stateless systems. This service is only enabled if full volatile mode is selected, for example by specifying "systemd.volatile=yes" on the kernel command line. This service runs only in the initial RAM disk ("initrd"), before the system transitions to the host's root directory. Note that this service is not used if "systemd.volatile=state" is used, as in that mode the root directory is non-volatile. SEE ALSO
