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 ...
