using UID-MIN

papillon has asked for the wisdom of the Perl Monks concerning the following question:

Hello, I am trying to add linux user. the system() call to useradd return an error that I don't get using the same line directly at linux prompt.

system ("useradd", '-K UID_MIN=2000', "-g $gid", "-m", "-p $hash", "$u
+ser");
[download]

I get the following error message:

configuration error - unknown item ' UID_MIN' (notify administrator)
[download]

If I print the line result instead and then directly put it at system prompt, the command execute succesfully.

$ useradd -K UID_MIN=2000 -g 2000 -m -p $... username
[download]

Any idea what cause the configuration error? Thanks

Each parameter (`"-g $gid"`, for example), should be separate parameters (`'-g', $gid`). You are creating a single parameter of the form `-g $gid` instead of two parameters (the flag and the value). This should be done for every flag+value that you have combined into a single parameter. --MidLifeXis	[reply] [d/l] [select]

Using separate parameter for each flag and value solve my problem. Thanks, Papillon	[reply]

This is just a guess, based on the error message: It looks like the leading space implies improper parsing - try this: `system ("useradd", '-K','UID_MIN=2000', "-g $gid", "-m", "-p $hash", " +$user");` [download] If your eyes hurt after you drink coffee, you have to take the spoon out of the cup. -Norm Crosby	[reply] [d/l]
