Save Linux command output to file

When running a command in SSH the outcomes and/or actions get displayed in the terminal. Certain commands spill over too many lines and get cut off, the solution to this is outputting the command to a file.

Saving this output can also be of use multiple times rather than needing to run the same command over and over again.

Redirecting and saving an output to a file is done with the > symbol:

command > outputfile.txt

Example that saves the df -h output:

df -h > diskspace.txt

To append (place below existing content in file):

df -h >> diskspace.txt

If you want the output in the console aswell as an output file use 2>

df - h 2> diskspace.txt

Save the output along with stderr (errors) use &> or &>> to append the output.
