Dear guys,
I am a software testing engineer of China.Recently,I am studying the skills
of Linux.When I try to do some exercises with "tr" command,I encounter a
problems.
the detail infomation is here:
I want to replace all the word of "root" to "administrator" in test.txt file.I
get a bit part of the file:
root 1 0.0 0.1 2008 768 ? Ss 21:03 0:03 /sbin/init
root 2 0.0 0.0 0 0 ? S< 21:03 0:00 [kthreadd]
root 3 0.0 0.0 0 0 ? S< 21:03 0:00 [migration/0]
root 4 0.0 0.0 0 0 ? S< 21:03 0:00 [ksoftirqd/0]
yeah,but when I finish the replace by execute command---- tr 'root'
'administrator' < test.txt
I found the result is not the same with my expected.
USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND
ammi 1 0.0 0.1 2008 768 ? Ss 21:03 0:03 /sbin/inii
ammi 2 0.0 0.0 0 0 ? S< 21:03 0:00 [kihaeadd]
ammi 3 0.0 0.0 0 0 ? S< 21:03 0:00 [migaaiimn/0]
ammi 4 0.0 0.0 0 0 ? S< 21:03 0:00 [ksmfiiaqd/0]
Yeah,maybe the word is too long,so it was trucate to admi,but the result is
ammi.
I don't know why this happen,and I cannot find a reasonable answer about it
from internet.So maybe it is a problem.
whatever,expect your reply.
your friend,
