There are many things you can do with the output of a command in Linux. You can assign the output of a command to a variable, send it to another command\/program for processing through a pipe or redirect it to a file for further analysis.<\/span><\/p>\n

In this short article, I will show you a simple but useful command-line trick: how to view output of a command on the screen and also write to a file in Linux.<\/span><\/p>\n

Viewing Output On Screen and also Writing to a File<\/span><\/strong><\/p>\n

Assuming you want to get a full summary of available and used disk space of a file system on a Linux system, you can employ the df command; it also helps you determine the file system type on a partition.<\/span><\/p>\n

df<\/p>\n

\"\"<\/a><\/p>\n

With the -h flag, you can show the file system disk space statistics in a \u201chuman readable\u201d format (displays statistics details in bytes, mega bytes and gigabyte).<\/span><\/p>\n

df -h<\/p>\n

\"\"<\/a><\/p>\n

Now to display the above information on the screen and also write it to a file, say for later analysis and\/or send to a system administrator via email, run the command below.<\/span><\/p>\n

df -h | tee df.log<\/p>\n

cat df.log<\/p>\n

\"\"<\/a><\/p>\n

Here, the magic is done by the tee command, it reads from standard input and writes to standard output as well as files.<\/span><\/p>\n
