Projects of the current working directory. An example for an absolute path is /home/asip01/test. e. Changing the current working directory: To change the current working directory use the cd command with a path name as the argument, i.e.: i. cd /home/asip01 ii. cd .. iii. cd ../asip02/ASIPMeisterProjects iv. cd ./dlx_basis/Applications f. Creating/Removing directories: the mkdir command takes a pathname as an argument and creates a new directory accessible via this path. The “-p” parameter tells mkdir to create any missing subdirectories as well. “rmdir” deletes empty directories. To remove non-empty directories use the “rm” command with the “-r” option (see below). Examples: i. mkdir ~/ASIPMeisterProjects/dlx_basis/Applications ii. rmdir ../dlx_basis/test1 iii. mkdir –p ~/some/non_existing/directory g. Listing directory contents: To examine directory contents use the ls command. Without parameters, it will show the file and directory names of the current working directory. The ls command has many parameters, all described in the man page. Typical ones are “-l” to provide a detailed listing, “-a” to show hidden files (filenames starting with a “.”), “-ltc” give a detailed listing with the last file modification time and sort by it (actually these are three parameters). Examples: i. ls ii. ls –l ../ASIPMeisterProjects iii. ls –ltc ASIPMeisterProjects/dlx_basis/ModelSim h. Moving and removing files: To move or rename a file use the mv command with the filename or directory as the argument. To remove a file use rm; the “-r” option causes recursive removal of subdirectories and their contents. Examples: i. mv Applications/tset Applications/test ii. rm /home/asip01/oldfile iii. rm –r ../dlx_basis - 8 -
i. Copying files: the cp command copies files and directories. Its arguments are: optional switches, then the source and the target. The “-r” switch enables recursive copying. Examples: i. cp TestData.IM TestData.IM-backup ii. cp –r dlx_basis dlx_custom • Shell operation: a. Input/Output redirection: Some programs read data on their standard input file descriptor (stdin), some write output to the standard output (stdout). Usually stdin is linked to the keyboard and stdout to the terminal screen. However, you can change this when calling a program. “someotherfile” will redirect stdout to write to “someotherfile” (if it doesn’t exist, it will be created, if it does, it will be truncated first – use “>>someotherfile” to append instead of truncate). Redirection is also possible to/from other processes via pipes: use “program1 | program2” to direct the output of program1 to the input of program2. Examples: i. ls –ltc >filelisting ii. ls | sort iii. cat >file2 (this appends the contents of file1 to file2). b. Job control: Processes started from the shell are often referred to as “jobs”. Usually, when the shell launches a program it will take control of the terminal and the shell will be suspended until the process terminates – the job “is running in the foreground”. To launch a job “in the background” – start it, but give control back to the shell immediately, append “&” to the parameter list. To list any jobs launched from this shell (they all have to be in the background), type “jobs” – this will give you the job-IDs with the program names and parameters of the jobs. To bring a job to the foreground, use “fg %job-ID” (substitute job-ID for the actual job ID). Sometimes you will want to temporarily stop a job – if the program is in the foreground, hit “CTRL-Z” (job suspension). To continue job execution in the foreground use “fg” as described above, or “bg %job-ID” to continue execution in the background. To terminate a job in the foreground, hit “CTRL-C” (send keyboard interrupt). Note that if a process is unresponsive (due to bugs – i.e. endless loop and signal processing disabled) it can ignore this; the only way to terminate it is to send a KILL signal (more on that further down). • Basic programs and commands a. Process/Activity listing. To view a complete list of running processes, use the ps program. It is mostly used with the “auxw” options to provide a complete and detailed listing. The output is usually quite long, so it is often piped into less or head. - 9 -
