In view of the fact that everyone has a certain strange when using VI, I will give birth to Buddha from the brothers [shell]. I hope that I will help you learn Unix, and I hope everyone can use HPUX. The experience is further extended to these experiences.

S indicates that S2 is a string to be replaced, he can be the same as S1 (if the same is used // instead), S3 is a replacement string

19.
At the same time Vi multiple files, Ctrl-Shift-6 returns to the previous file, switch between this VI file and the last VI file.
But I found a bug: After switching to the previous file with Ctrl-Shift-6, use: args to view the multi-file VI status,
The current VI is still displayed at the bottom of the screen.
(By HP-UX, Solaris, AIX passed)
You can also use:
: e #
Switch

SCO's VI should be added to the same character before text
% s / ^ / to add content / g to add the same characters after text
% s / $ / to add content / g
twenty one.
How to remove the text in the text? It is not necessary to use binary to pass back to ASCII back, and implement it with the shell or UNIX statement.
Cat filename | TR -D '15> Newfile
Different UNIX systems have some other different commands, such as DOSCP
SED can also achieve this feature.
Dos2Unix filename filename2
on the contrary
UNIX2DOS filename filename2
Use in VI: $ S / ^ m //g
^ Is CRTL-V CRTL-M
