    Got set of articles. After 30+ years of *nix experience, I learned quite a bit, and these articles are going into my archives of “useful” stuff! :-)

    Thanks for your efforts. I see a great career for you in this domain.

    P.S. I am a senior systems engineer for a tier-one tech company and help handle performance engineering for thousands of Linux servers world-wide, supporting 150M+ users.

    Problem :
    # vgscan; pvscan; lvscan
    # ^scan^display

    gives :
    #vgscan; pvscan; lvdisplay

    Solution: full substitution with gs :
    # vgscan; pvscan; lvscan
    # !:gs/scan/display


    #vgdisplay; pvdisplay; lvdisplay

      @ ZIADI Mohamed-Ali, True ^foo^bar works with single substitution only, for multiple substitution, wait for our next article.

    Awesome pro tips. I completely forgot about the “factor” command, I could have used that on Monday! “the more you know”

    For the > command, you might say “truncate” instead of flush. I can’t be the only one here thinking flush as in write all changes to disk from cache.

    the command “fc” from bash is also quite nice
