A free Basic UNIX-training with muLinux

In order to store this exercise on a DOS diskette, we put these into the floppy disk drive, mounten the drive after / a and change into the directory / a .
/ # mount /dev/fd0 /a
/ # cd /a

Converting Text Files between DOS and Unix

If a Unix text file in DOS or Windows is continued to process, then the representation of the line-makeup takes place not correctly. Thus become with simple text editors, like z. B. notepad.exe , in place of a page make-up only strange characters represented. More fastidious text editors, e.g. the Windows version of vi , also Unix text files can correctly read. Becomes a DOS text file into that vi - wordprocessor loaded, then appears ^M - characters at each line end.

In order to avoid problems, the text files should be converted. There are two programs for it under Unix. unix2dos Converted of Unix to DOS and dosùnix Converted of DOS to Unix. The 2 is called in English " two ", thus like " to " (English too) expressed unix2dos is thus actually " Unix to of DOS " to be called.

Around a Unix text file into a DOS text file to convert the following instruction line serves. cat outputs the file content. The output becomes however pipe by means of directly too unix2dos rerouted. unix2dos the each line-makeup works the character as a filter, new LINE adds.

cat Unixtextfile | unix2dos > DOStextfile

Over e.g. a copy of the file /etc/passwd after DOS to convert and on our DOS diskette store, we input the following instruction:

/# cd /a
/a # cat /etc/passwd | unix2dos > passwd.txt

The DOS diskette can be taken after the removal of the mount allocation from the floppy disk drive, in order to process it thereafter in a Windows PC. File passwd.txt can then with one doubleclick in the Windows Notepad to be edited. Like know thus a text file with that vi write, into the DOS title format convert and on a gemountete DOS diskette copy. Subsequently, then this text file under DOS or Windows can be continued to process. Turned it goes naturally also.

For conversion of DOS text files in Unix text files the same principle is used. dosùnix removed however in each case the character new LINE .

cat DOStextfile | dos2unix > Unixtextfile

In other Unix versions the syntax of these instruction is every now and then very different.

Around this exercise to terminate we lift those mount - allocation of our work diskette up.
/ a # cd /
/ # umount / a
/ # _
