In dbin, create scripts for each of the DOS commands below: DOS Cd Md Rd Dir Copy Del Type Rename Edit 3. In dbin, create a script called unixtodos that: · sets the user prompt to show the current directory · adds the your dbin directory to the PATH 4. In dbin, create a script called dostounix that restores the: · path · and the prompt 5. In dbin, as part of the DOS environment, write a script called compile, that takes the filename of a C source program, compiles it using the gcc compiler and creates a executable file using the filename [i.e.] $ compile hello $ ls -F hello.c hello* $ 6. System Calls - Create a new command for the DOS environment called createfile that uses a system call to create a blank UNIX file with the following default file permissions -rw-r--r-- 7.

hello there, my name is john and i have a problem with a networking assement. i need ideas for a small network. and some information on unix shell scripts

Paul, Reference the above problems, do you know any unix? If not, it would be advisable to go out and get a good boot, however the above scripts should only have to be a few lines. I will give you the equivalent unix commands and that should atleast point you in the right direction. DOS UNIX Cd chdir Md mkdir Rd rmdir Dir ls Copy cp Del rm Type cat (or more) Rename mv Edit vi (not very friendly!) 3. Your prompt is stored as variable PS1 and path can be added useing: PATH=$PATH:$HOME/dbin I don't want to tell you all the answers but if you need any more help then please contact me. Regards, Anthony.
