Tartalomjegyzék

Bash

You have to write a bash script: write commands into a file, similar like the ones in konsole. The commands should do the following:

  • Make a directory called Info1 in the home folder (mkdir)
  • enter that directory (cd)
  • download the file http://sandbox.hlt.bme.hu/~gaebor/ea_anyag/Info1/williamblake.txt in the current directory (wget)
  • count the words in that file (wc) and write it in a file words.txt (redirecting)
  • erase the downloaded file (rm)
  • finally, enter the parent directory (back to home folder)

script

You can try the commands in konsole, and write them in a file with extension .sh, attach the .sh file to your email.

You can execute the commands in the file at once with bash

   bash >>something.sh<<

Hint

See the manuals like:

   man cd
   man wc
   man ...
