In the above code, multiple conditions are used using the OR operator. To achieve a complex behavior, multiple conditions can also be used with the while loop using logical operators that include AND (&&), OR (|
i=0 while [ $i -lt 100 ]; do i=`expr $i + 1` echo $i done i=0 until [ $i -ge 100 ]; do i=`expr $i + 1` echo $i done For other until loop examples such as integer comparison, string comparison and multiple conditions, refer to those demonstrated in the while loop....
While ‘else if’ is a powerful tool for handling multiple conditions in bash scripting, it’s not the only one. An alternative approach is the ‘case’ statement. ‘Case’ statements can be more readable and easier to maintain than a long list of ‘elif’ conditions, especially when you’...

So far, so good. But do you know that you may have multiple conditions in a single by using logical operators like AND (&&), OR (||) etc? It gives you the ability to write complex conditions. Let's write a script that tells you whether the given year is a leap year or not. ...
In this article, I present a few tricks to handle error conditions—Some strictly don't fall under the category of error handling (a reactive way to handle the unexpected) but also some techniques to avoid errors before they happen.Case study: Simple script that downloads a hardware report ...
nvm use will not, by default, create a "current" symlink. Set $NVM_SYMLINK_CURRENT to "true" to enable this behavior, which is sometimes useful for IDEs. Note that using nvm in multiple shell tabs with this environment variable enabled can cause race conditions....
Example 7: until Loop with Multiple Conditions Like the previous example, this script also uses anuntilloop. However, instead of one condition, it uses multiple conditions to perform different actions based on the counter value. The script counts from 1 to 10 and performs specific actions for ...
default for future RIGHTARROW and LEFTARROW commands. While the text is scrolled, it acts as though the -S option (chop lines) were in effect. ESC-( or LEFTARROW Scroll horizontally left N characters, default half the screen width (see the -# option). If a number N is specified, it...
