Common DOS commands translated back to UNIX:
cd ---exactly like cd
clear ---exactly like cls
cp ---very much like copy
ls -al; df -k | more ---kind of like dir /p
mv ---very much like move
uname -sr ---kind of like ver
Other Unix commands I really need right about now:
cat ---concatenate files
chgrp -R <group name> <folder name>/* ---changes the group of <folder name> to <group name> and all of its sub-folders/files
chmod a+r <filename> ---makes <filename> readable to all
chmod a+x <filename> ---makes <filename> executable to all
chmod -R g+w <folder name>/* ---adds group-level write privileges to <folder name> and all sub-folders/files
chown -R <user name> <folder name>/* ---changes the owner of <folder name> to <user name> and all of its sub-folders/files
du -sk <path name> ----returns the amount of disk space <path name> occupies in KBs
find . -name "*.html" -print | sort ---displays a sorted list of files with ".html" in their names in the directory (and any subdirectories) where the command is executed
kill -9 <process ID> ---"really" stops a process with id <process ID>
passwd <user name> ---changes the password of <user name>
ps -fu<user name> ---returns the processes run by <user name>
rm -r <folder name> ---remove <folder name> and all of its sub-folders/files
sort -o <destination file> <source file> ---e.g.: sort -o .newsrc .newsrc
su <user name> ---creates the shell of <user name>; to terminate this session and return to the original login enter EOF (usually Ctrl+d)
tar -xvf <archive name(s)> ---extracts one or more tape archive files (tar files) and prints the name(s) of the file(s) stored in the archive to the console
which <command name(s)> ---determines which file is associated with <command name(s)> (separated by spaces)
who ---determines who's logged in the system
Search for literals with grep and fgrep ("fast" grep).
To shutdown the system use the command
/usr/sbin/shutdown -y -g0 -i0
To start the system use boot.
Don't forget all those kick-ass compression commands like pack and compress! Also note that .tgz implies .tar.gz---which in turn implies the compression application gunzip.
Use the vacation command for vacations.
