This can be done using the logsave command. To save the output of a command to a log file using logsave, type the command using the following syntax:
logsave (path and name of log file)'(command)'
Notice how there are single quotation marks around the name of the command. Although these are not necessary for all commands, it may be required for commands containing spaces or other special characters. Unlike in Windows, where the output of the command can either be written to standard output or a log file, logsave will write a copy of the output to both.
If the command has progress bar output, you may want to use the -s argument to prevent these lines from being written to the log file. Also, by default logsave does not append the log file, but instead overwrites it, so if you are using a bash script or something to write a log of output, the -a argument may be useful to ensure that the previously written text is appended instead of being replaced.
Viewing a file:"less [filename]"viewing the standard output of a command:"[command] | less"
The tail command can be used to output the last part of a text file. The default is to show the last 10 lines of a file and options are available to override this.
In Linux the chmod command is used to set file permissions.
It depends on the shell interpreter you are using, but in general the I/O redirection operators are >, >>, |.
Pipes are useful for redirecting inputs or outputs from a program instead of using stdin or stdout. For instance, piping the output of a command to a text file.
A Unix memory dump is usually placed in a file called 'core'. You merely delete the file with the 'rm' command, as you would any other file on the system. For Linux/Unix on the mainframe, the file is called CEEDUMP (if the C plus plus runtime LE library is being used), and you delete it the same way.
The Unix/Linux tee command permits the forking of a data pipe in a shell script or at the command line. The teecommand does this by both writing it's standard input to a file and to it's standard output simultaneously. Most implementations of tee provide for both file overwrite/creation and file appends by command line switch options.
The simplest utility for viewing file content in the Linux Terminal, (Terminal as command promt also called DOS in Windows) its called the file command.

You would use a pipe. For example. ls | grep cool The output of ls(the list of files in your current directory) is given to grep. Grep then finds and prints file names that include the word cool in them.
The mount command instructs the kernel to access the file system on a partition or device.
if the file is allready runnable you can type in the terminal: ./filename
