Let me be perfectly clear: ed(1) is the standard Unix text editor. If you don’t know ed, you’re not a sysadmin. You're a mere dabbler. A dilettante. Deficient.
Forty years after ed’s introduction, internationally acclaimed author Michael W Lucas has finally unlocked the mysteries of ed for everyone. With Ed Mastery, you too can become a proper sysadmin.
Ed Mastery will help you:
• understand buffers and addresses
• insert, remove, and mangle text
• master file management and shell escapes
• comprehend regular expressions, searches, and substitutions
• create high-performance scripts for transforming files
You must be at least this competent to use this computer. Read Ed Mastery today!
(This special edition exists for the people who believe that women don't belong in technology books. Any third-person singular pronouns that appear in the standard edition, for normal people, are female. Those who believe that women don’t belong in tech books may purchase this special “Manly McManface” edition, where all third-party singular pronouns are masculine.
To compensate for this edition’s much smaller market, though, the Manly edition is "unfortunately" pricier than the standard edition. That’s basic economics.
Also, one dollar of the author's proceeds from each sale of the Manly McManface Edition will be donated to his local chapter of Soroptimists International.)
