BRIEF LINUX MANUAL FOR WINDIE STUDENTS
Robert J. Rutten
Institutt for Teoretisk Astrofysikk Oslo
This very brief unix/lunix tutorial was initially written for
operating-system-challenged DOT students ("windie dotties"):
I also have Ubuntu installation recipes at
and some unix/linux recipes at
mkdir somename # make new subdir
pwd # print working directory
cd .. # go one back up; one . means "this directory"
cd # go to top = your "root" = ~/.
cd ~rutten # go to my root ("home") directory
chmod 644 file # open file for reading by others
chmod 755 dir # make directory accessible for others
ls # list directory content
ls -l # more info
ls -aF # list also system files starting with a .
cp file dir/. # copy file into other directory
cp -upr dir path # copy dir with all in and under to other location
mv filea fileb # mv = move, to another dir or rename
rm file # rm = remove = delete
rm -rf dir # delete dir with everything in and under it
#!/bin/csh first line of a script (shell eg csh, bash, etc)
cd ~/bin # directory to put executable scripts in
chmod 755 script # make script executable, also by others
rehash # activate new scripts
file copy to or from remote computer
scp firstname.lastname@example.org:/home/students/user/file .
# copy file from there to here
## first time: say yes at authentication question
scp file email@example.com:/home/students/user/.
# copy file from here to there
scp -r firstname.lastname@example.org:/home/students/user/dir .
# copy dir with all in it / under it from there to here
ssh -X email@example.com # open remote session with X windows
