I have an exercise to put in a file some data (*conf from some directories) and need to do this in background. I did it and I am wondering what is the meaning of output messages:
[A@localhost tests]$ ls -ld /etc/*conf /usr/*conf > test1_6_conf.txt 2>&1 &
Enter rises this row:
[1] 2533
what does it mean?
After other Enter, another messages appear
[A@localhost tests]$
[1]+ Exit 2 ls --color=auto -ld /etc/*conf /usr/*conf > test1_6_conf.txt 2>&1
What does it mean? What is "Exit 2"?
Enter an check results – seems to be all OK.
[A@localhost tests]$
[A@localhost tests]$ ls -l test1_6_conf.txt
-rw-rw-r--. 1 A A 2641 Nov 22 14:19 test1_6_conf.txt
[A@localhost tests]$
I am using CentOS 6.4, Gnome Terminal Emulator.

It is exit status of
ls
. See man for ls:I guess the reason is that you have lots of *conf files in
/etc
and no *conf files in /usr. In factls -ld /usr/*conf;
would have had the same effect.So If I do on my computer
ls
for an existing file:And for a file that does not exists:
Or as a background process ls for a a file that does not exists:
