Topic #: 6

[All GSNA Questions]

John works as a Network Administrator for Perfect Solutions Inc. The company has a Linux-based network. John is working as a root user on the Linux operating system. He has a data.txt file in which each column is separated by the TAB character. Now, he wants to use this file as input for a data mining software he has created. The problem preventing him from accomplishing his task is that with his data mining software, he has used TAB as a delimiter to distinguish between columns. Hence, he is unable to use this file as input for the software. However, if he somehow replaces the TAB characters of the file with SPACE characters, he can use this file as an input file for his data mining software. Which of the following commands will John use to replace the TAB characters of the file with SPACE characters?

Aexpand -t 1 data.txt > data.txt

Bcat data.txt

Cchmod 755 data.txt

Dtouch data.txt

Show Suggested Answer

Suggested Answer: D

In Unix, the /etc/securetty file is used to identify the secure terminals from where the root can be allowed to log in.

Answer B is incorrect. In Unix, the /etc/ioports file shows which I/O ports are in use at the moment.

Answer A is incorrect. In Unix, the /etc/services file is the configuration file that lists the network services that the system supports.

Answer C is incorrect. In Unix, the /proc/interrupts file is the configuration file that shows the interrupts in use and how many of each

there has been.

I bet John's data mining software is as confusing as this question. Gotta love tech problems!

Seriously? Chmod and touch? Those commands have nothing to do with replacing characters in a file. I need to brush up on my Linux skills.

Wait, what? I thought we were supposed to use cat to read the file. This is definitely trickier than it looks.

A) Oh, right. Then it must be 'expand -t 1 data.txt > data.txt'.

B) No, that won't work. You need to replace TAB with SPACE.

Hmm, I was thinking about using sed, but expand seems like a more straightforward solution. Nice find!

User 1: Thanks! I think expand -t 1 data.txt > data.txt should do the trick.

The expand command is the way to go! It will replace the TAB characters with spaces, making the file compatible with the data mining software.
