UNIX for Dummies Questions & Answers

What is the syntax for recording command in vi. If I want to repeat a command over and over.

My file is
12/01/05,,adsmte,9,0,0
12/02/05,,adsmte,12,0,0
12/03/05,,adsmte,10,0,0
12/04/05,,adsmte,11,0,0
12/05/05,,adsmte,10,0,0
12/06/05,,adsmte,10,0,0
12/01/05,,tsmpc1,57,1,2
12/02/05,,tsmpc1,83,4,2
12/03/05,,tsmpc1,89,6,2
12/04/05,,tsmpc1,31,1,0
12/05/05,,tsmpc1,35,1,0
12/06/05,,tsmpc1,52,5,2
12/01/05,,tsmpc2,86,2,2
12/02/05,,tsmpc2,94,5,1

and I want to insert Thu,Fri,Sat,Sun in between ,, without having to type that one at a time on each line.
I this is something I have done before but can't recall how.

If your input file is 'test' you can do it without vi'ing it - which has to be easier. Try this:

awk -F',' '{ print $1",Thu,Fri,Sat,Sun,"$3","$4","$5","$6 }' test > test1

where test1 is an output file - which looks like this:

12/01/05,Thu,Fri,Sat,Sun,tsmpc2,86,2,2
12/02/05,Thu,Fri,Sat,Sun,tsmpc2,94,5,1

HTH,

Thanks for the reply but what I am trying to achieve is
12/01/05,Thu,adsmte,9,0,0
12/02/05,Fri,adsmte,12,0,0
12/03/05,Sat,adsmte,10,0,0
12/04/05,Sun,adsmte,11,0,0
12/05/05,Mon,adsmte,10,0,0
12/06/05,Tue,adsmte,10,0,0
12/01/05,Thu,tsmpc1,57,1,2
12/02/05,Fri,tsmpc1,83,4,2
12/03/05,Sat,tsmpc1,89,6,2
12/04/05,Sun,tsmpc1,31,1,0
12/05/05,Mon,tsmpc1,35,1,0
12/06/05,Tue,tsmpc1,52,5,2
12/01/05,Thu,tsmpc2,86,2,2

sed 's=12/01/05,,=12/01/05,Tue,=;s=12/02/05,,=12/02/05,Wed,=' <input >output

That way works Perderabo but I'm really trying to recall how to record repetitive keystrokes in vi.

There's several ways do that in vi...maybe you were using map
:map ; o123^V^M^V^[

^V = control V
^M = cntrol M
^[ = escape

Now ; will add a line with just 123.
