which command prevents displaying the stata command in a do file

[jerome falken]

while quietly silences everything, is there a command or prefix that allows a stata command not do display itself during the evaluation of a do file, however I do want to see the output of such command when the script runs.

[Ali Atia]

You can use noisily within quietly to display a command's output while suppressing the command itself. For instance:

quietly{
    clear
    set obs 50
    gen x = runiform()
    gen y = runiform()
    noisily reg y x
}

Which outputs:

. quietly{

      Source |       SS           df       MS      Number of obs   =        50
-------------+----------------------------------   F(1, 48)        =      0.00
       Model |  .000209382         1  .000209382   Prob > F        =    0.9522
    Residual |  2.76747995        48  .057655832   R-squared       =    0.0001
-------------+----------------------------------   Adj R-squared   =   -0.0208
       Total |  2.76768933        49  .056483456   Root MSE        =    .24012

       _cons |   .5235474   .0629634     8.32   0.000      .396951    .6501438

perfect, I wouldn't have guessed it

[William Lisowski]

A slightly different approach that separately displays of the commands and their output. For those like me who need to see their commands in their log files to remember what they were doing,

. foreach dummy in dummy {
  2.     clear
  3.     set obs 50
  4.     gen x = runiform()
  5.     gen y = runiform()
  6.     regress y x
  7. }
number of observations (_N) was 0, now 50

      Source |       SS           df       MS      Number of obs   =        50
-------------+----------------------------------   F(1, 48)        =      0.15
       Model |  .012955144         1  .012955144   Prob > F        =    0.6982
    Residual |    4.087633        48  .085159021   R-squared       =    0.0032
-------------+----------------------------------   Adj R-squared   =   -0.0176
       Total |  4.10058815        49  .083685472   Root MSE        =    .29182

------------------------------------------------------------------------------
           y |      Coef.   Std. Err.      t    P>|t|     [95% Conf. Interval]
-------------+----------------------------------------------------------------
           x |   .0614949   .1576642     0.39   0.698    -.2555103    .3785001
       _cons |   .4928259   .0786106     6.27   0.000     .3347686    .6508831

very helpful, is there a variation around Ali Atia that doesn't display "quietly{"

[William Lisowski]

Surprisingly, but just technically, yes, although this may not really be an improvement in what it displays.

set output error

clear
set obs 50
gen x = runiform()
gen y = runiform()
noisily display "this is my regression"
noisily reg y x
predict yhat 

set output proc
summarize y yhat

. set output error
this is my regression

interesting, this is extremely helpful; sometimes I like to see the concise data.

[Jawad Al-Lawati]

Thank you, Mr Atia, for a great solution for an issue I was looking for!

Also, any idea if you can create a shortcut for a command I use very frequently like "codebook"
