Below are some useful basic linux commands:
| Command | Example | Description |
|---|---|---|
| cd | cd /usr/tmp cd test |
change directory |
| cd .. | back to parent directory | |
| ls | ls | to list files and directories |
| ls /usr/tmp | to list files and directories in the particular path | |
| cp | cp /usr/test.txt /home/test.txt | copy file |
| cp -i /usr/test.txt /home/test.txt | copy file, you will be prompted before it is overwritten | |
| rm | rm abc.txt | remove/delete a file |
| rm -rf mydir | remove all files & subdirectories from a directory | |
| rm -rf mydir | remove all files & subdirectories from a directory | |
| rmdir | rmdir mydirectory | remove empty directory |
| rmdir | rmdir mydirectory | remove empty directory |
| mkdir | mkdir newdirectory | create a directory or folder |
| mv | mv /usr/file.txt /home/ | move file to another directory |
| mv file.txt file2.txt | rename a file | |
| find | find -name missingfile.txt | the command will search the file in current and sub-directories |
| find / -name missingfile.txt | the command will search the file in root and sub-directories | |
| find -name ‘*.txt’ | the command will search the file end with .txt in current and sub-directories |
Here is a slightly more efeificnt way of doing the same thing:find ./ -name .svn -exec rm -rf {} \;When you use -exec find will execute the command for every result returned via the find query into the argument {}Another useful command is to only perform and operation on files that have not been added or modified. You can do this like so:svn status | grep ? | awk {print $2}’ | xargs rm -rfThis would remove any file that has been added to the repository.Breaking it downsvn status will return results like this:? fooM build/projects/Community.imlM build/build.propertiesPiping it through grep ? will give you:? foo Awk can be used to print out the column we want that is what the print $2 part of the awk command is for.foofinally pass the results to xargs rmHope this is interesting.cheers,A.J.
