the for loop will be executed a total of 5 times, once for each item in the list. The current item from the list will be stored in a variable “varname” each time through the loop. This “varname” can
This “varname” can be processed in the body of the for loop. Method 2: Bash For Loop using C like syntax The second form of the for loop is similar to the for loop in “C” programming language, which has three expressions (initialization, condition and updation). for (( expr1; e...
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...
Write a Bash script that uses a for loop to iterate over a range of numbers from 1 to 20 and prints only the odd numbers. Code: #!/bin/bash# Iterate over a range of numbers from 1 to 20for((i=1;i<=20;i++));do# Check if the current number is oddif((i%2!=0));thenecho...
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 复制 #!/bin/bash for i...

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
for i in {1..5} do echo $i done # like this, you can quickly generate a range of numbers # This also works downwards: for i in {5..1} do echo $i done9 changes: 9 additions & 0 deletions 9 for-loop-variables.sh @@ -0,0 +1,9 @@ #!/bin/bash key_val="obama=60 tru...
