In a monetary policy move at the end of 2016, the U.S Federal Reserve Bank, the country’s central bank raised interest rate citing a stronger economic growth and rising employment.

Linux Fundamentals part 4 final

Below are questions related to the command line use of Linux.  You can use the videos, man pages, and notes to answer these questions. 

Remember that Linux is CASE SENSITIVE.  Rm and rm are NOT the same command.  I will count off totally for a question if you do not take this into account.

For each command give me the ENTIRE COMMAND SEQUENCE.  If I ask you  'What command would I use to move the file one.txt to the parent directory and rename it to two.txt?", the answer is NOT 'mv'. That is only part of the command. I want the entire command sequence.

16. Find all files under ~ whose content contain the keyword taco OR Taco OR taCo OR tacO. NOT all variations in case for 'taco', but just the variations listed meaning a keyword of tAco, tACO, tACo, etc, will not produce a result.

17. Find all files under the current directory which ends in '.txt' (just the .txt not the single quotes) and use -exec to create a listing of each files inode number. Since we're using -exec, this means we will call another command to produce the inode based on the results found. What command do we use to make listings? Now you just need to find how to make it produce an inode result. To the man page!

18. What command would I run to update the database of file names used by the locate command?

19. Find all files under the /var directory with a size less than 1 kilobyte. Use -exec and an appropriate command to copy those files to ~/Documents/FallFun/sep.

20. Find all files under the ~ directory that are named 'Picard' ignoring case.

Using the C language:

In the old days, data was stored on punched cards of 80 or 96 columns.

Presume your job is to update a database to include the newly found data in the file punchcard.txt
into a currently used data base. In order to do that, you must read in the data in columnar format
and convert it to comma separated fields so it can be imported.

Using buffered I/O functions (e.g. fopen, fclose, fprintf, fscanf, fread or fwrite, fgets, fgets, etc),
read the columnar data in punchcard.txt into your program. It has the following fields:

   unsigned int user_number 6 columns
   char name 32 columns
   char address 32 columns

Write the data out to a file called import.txt which is of the following CSV format for each line:

   user_number,name,address<carriage return>

If the data in name or address contains a comma, it must be delimited with double quotes around
it. Make sure you remove all extraneous spaces in front of, or behind the data so that the entry in
the import.txt file has no extraneous spaces which is not part of the data. This is often called
"trimming" the data.

punchcard.txt contains...
