+# Some tips and tricks I've picked up along the way
+# these are some things I use almost everyday
+
+# see all the commands you've run
+# the amount set depends on $HISTSIZE
+history
+
+# you can pipe into grep to search in history
+history | grep "search-term"
+
+# I use pipe a lot
+# this lets me view all subdirectories in less
+# and it acts like vim
+ls -R | less
+
+# when you found a command you want to rerun from history
+!100
+
+# rerun last command:
+!!
+
+# rerun last command but with sudo
+sudo !!
+
+# redirecting output to a file
+uname -a >uname.log
+
+# the > truncates the file, it will erase everything and
+# add in the new contents
+#
+# the >> appends to the file, it will add in after the last
+# the file
+
+# awk is useful for parsing text from previous output
+nmcli c show | awk '{ print $1 }'
+nmcli c show | grep '\-\-' | awk '{ print $2; }' | while read con; do sudo nmcli c delete $con; done
+
+# just run a really long command but made an error?
+# fix command -- this will put the command into your system's
+# text editor (nano,vim,emacs,etc)
+# as soon as you save and quit, it will run with your changes
+fc
+
+# how about an on-the-fly shell script?
+# hold: control + x + e
+# acts much like fc
+# write out the script you want and save and quit
+
+# disown
+# if you have a really long running process that your server might kick you off
+# depending on the ssh timeout
+# run control + x to put it in the bg
+bg
+disown -a
+exit
