In this code block, we first assign the value of$RANDOMto the variablerandom_number. Then, we print the value ofrandom_numberusing theechocommand. Each time you run this script, a new random number between 0 and 32767 will be printed. The Range of $RANDOM The$RANDOMvariable generates an ...

Edit 1:Don't use rand(): a guide to random number generators in C++Please read this once to generate random numbers efficiently thanksGLAYS. Edit 2:Updated rand() with mt19937 rng(). Great work! Stresstesting is very useful and sometimes the only thing you can do to catch bugs or to...
Since we still rely on this number, it will limit our max random number generator to 32768 values. We use a bash while loop with the bash null command to iterate over a series of $RANDOM numbers until we get one below the max value. We use a bash if statement to ensure that we ...
Lines 11 and 12, I enable error trace and added a ‘trap’ to tell the user there was an error and there is turbulence ahead. You may want to kill your script here instead, I’ll show you why that may not be the best. Line 20, if the directory doesn’t exist, then try to cre...
seeds the random number generator. .B REPLY is the default variable used by the .B read builtin when no variable names are supplied as arguments. The .B typeset builtin is used to define variables and give them attributes such as \fBreadonly\fP. Bash arithmetic allows the...
