Everyone knows that Linux is a Powerful Operating System due to his BASH and Commands...
BUT....
I know that DOS is also a Powerful Operating System...
In this POST I will show you a Command Comarison of RH- Linux and MS - DOS..
Command Comparison: |
DOS Command | UNIX or Bash Command | Action |
DIR | ls -l (or use ls -lF)(-a all files) (df -k Space remaining on filesystem) | List directory contents |
DIR *.* /o-d DIR *.* /v /os DIR /s DIR /aa | ls -tr ls -ls ls -R ls -a | List directory contents by reverse time of modification/creation. List files and size List directory/sub-directory contents recursively. List hidden files. |

RMDIR RD | rmdir | Remove a directory |
CHDIR | pwd | Display directory location |

FC | diff | Compare two files and show differences. Also see comm, cmp, mgdiff and tkdiff. |
SET | set and env | List all environment variables |
SET variable=value echo %variable% | set export variable=value echo $variable | Set environment variables Show environment variables |
ECHO text | echo text | Echo text to screen |
SET variable | setenv (for C shell) or export VAR=val (for Korn shell. Also VAR=val) | Set environment variables |
PATH PATH %PATH%;C:\DIR | echo $PATH PATH=$PATH:/dir | Display search path for executables. Set PATH environment variable. |

BACKUP files A:\ | tar -cvf /dev/fd0 files mdir, mcopy doswrite -a file (AIX only) | Save files to floppy. |
RESTORE A:\ files | tar -xvf /dev/fd0 files mdir, mcopy dosread -a file (AIX only) | Read files from floppy. |
ATTRIB [+r|-r] [+a|-a] [+s|-s] [path\file] /s | chmod | Change file permissions. DOS: +:set to -:remove r:Read only a:Archive s:System /s:recursively |
ATTRIB +h or -h | mv file .file | Change file to a hidden file - rename file with prefix "." |
PRINT | lpr | Print a file |
CALL COMMAND /C (DOS), CMD (NT) | source script (cshrc) . script (bash) sh script | Execute script from within batch shell. |
MEM | free top | Show free memory on system |
TASKLIST (WIN2K, XP) | ps -aux top | List executable name, process ID number and memory usage of active processes |
MSD | lsdev | Show system info (Command borrowed from AIX) |
SCANDISK DEFRAG C: | fsck debugfs | Check and repair hard drive file system |
CHDISK | du -s | Disk usage. |

PING | ping | Send packets to a network host |
TRACERT | traceroute | Show routes and router hops to given network destination. |
IPCONFIG (NT) WINIPCFG (Win 95...) | ifconfig | Display/configure network interface |

WIN | startx | Start X-Windows. |
REBOOT | shutdown -r now | Reboot system. |
To find out how to do something on UNIX simply type "man -ksubject_matter". This will do a key word search for all commandsdealing with the subject matter. Then use the appropriate command. Onlinemanuals are available on all the commands by typing "mancommand_name".
