rshell

general:

This program mimics the bash shell by taking in commands and performing their tasks as usual. You can perfrom tasks such as

• ls -lists the files in a directory.

  • with all flags

• cat -displays everything in a file

• echo -prints out what is passed in as a parameter

• mkdir -makes a new directory

• "#" -everything after this is a comment and does not get executed

• & -runs program in background allowing terminal to continue

• exit -typing exit will kill the program

• rm -removes a file

• rmdir -removes a directory

• cd -changes the working directory

  • cd ..(changes to one directory back in the path)

  • cd (changes to home directory)

  • cd [directory name] (changes to that directory)

• for more features view the /bin page on your computer

UPDATE:

(1)

• the ls command has now been written

• ls can take the parameters [no parameters],[-a],[-l],[-R] and any combination on them all

• ls can also take file names which will output the contents inside the files or directories

(2)

• the cd(change directory) command is now working properly

• ^c does not kill the whole program, just kills program running inside rshell

how to run rshell:

• type make, this will build and compile the program

• to run, type bin/rshell

• to clean the file, you type make clean and this will discard executibles and object files

how to run the ls command:

• type make, this will build both rshell and ls

• type bin/ls [argument lists]

bugs:

• when an error is produced, it sometimes gets printed on the line with the "$" and the next line does not have a "$", just need to hit enter again

• "#" right after a command does not work properly

  • for example (ls# -a) will not execute ls

• "#' does not work before commands

• when "exit" is typed, sometimes it will need to be typed twice, but it will still exit

• ls -R does not work at all

• ls with more than one filename does not work
