When I used the wrong flag in a command I received very unusual output:

( I was trying to prevent the colorization of the grep output )

administrator@updatestestsvr:~$ sudo dmesg |grep -i -nocolor cpu
LinuxTestRemoteOffice.zip
lscpu-out.txt
directsetup/UEMSAgent.msi
directsetup/UEMSLinuxAgent.zip
directsetup/UEMS_LinuxAgent.bin
directsetup/UEMSMacAgent.zip
QualysCloudAgent.deb
.bash_history
testorgmainoffice06f8c4-5.7.8836-installer-x86-64.deb
.config/htop/htoprc
administrator@updatestestsvr:~$

------

Compare with the output of ls -la of current directory:

administrator@updatestestsvr:~$ ls -la

It appears as thought the grep'ing of that dmesg returned a subse of the files in the current directory.
