Example 5: C-style for Loop #!/bin/zshfor((i=1;i<=5;i++))doecho"Number:$i"done Practical Example: Creating Backup Files Create the script file backup.sh: nano backup.sh Add the following content: #!/bin/zshsource_dir="/path/to/source_directory"backup_dir="/path/to/backup_direct...
echo "Number: $i" done Over Array Elements While one can use the for loop for numbers and strings, programmers can even leverage the same to repeat over a range. For example, we will state an array - Players and iterate over each of the elements of the range. PLAYERS=('Cristiano Ronal...
This type of for loop is characterized by counting. The range is specified by a beginning (#1) and ending number (#5). The for loop executes a sequence of commands for each member in a list of items. A representative example in BASH is as follows to display welcome message 5 times wit...
The script uses a for loop to iterate over a range of numbers from 1 to 20. The loop variable 'i' represents each number in the range. Within the loop, an if statement checks if the current number ('i') is odd using the condition i % 2 != 0. If the condition evaluates to true...

The range is specified by a beginning (#1) and ending number (#5). The for loop executes a sequence of commands for each member in a list of items. A representative example in BASH is as follows to display welcome message 5 times with for loop: 代码语言:txt AI代码解释 #!/bin/bash ...
The count-controlled loop repeats the execution of a section of code for a certain number of times. The counting can be upward or downward with varying step size. This loop generally uses a for loop construct. The condition-controlled loop repeats the execution of a section of code until a...
Bash for Loop With a Number When working with numbers in the bash loop, you can use a span instead of specifying the items individually. To do so, add the range in curly braces separated with double dots: for i in {1..5} do echo "$i" done ...
In bash scripting, loops are used to repeat a block of code until a certain condition is met. When combined with ‘else if’, you can create scripts that handle a wide range of scenarios. Here’s an example of a script that uses ‘else if’ within a ‘for’ loop: ...
Here’s a simple example of a ‘for’ loop in Bash: foriin123doecho"Processing number$i"done# Output:# Processing number 1# Processing number 2# Processing number 3 Bash Copy In this example, the ‘for’ loop iterates over the numbers 1, 2, and 3. For each iteration, it runs the...
