Bash For Loop In One Line with Files # for i in *; do echo "Found the following file: $i"; done # for i in `cat filelist.txt`; do echo ${i}; done; if a line may include spaces better use a while loop: # cat filelist.txt | while read LINE; do echo "${LINE}"; done ...
Why you can use a bash for loop in one line If you use bash on the command line, this will not guarantee that for loops are inserted into the script. In order to prevent this, it is easiest to use loops directly on the command line and then there will be no problems. How to use...
Example 03: Nested For Loop in One line The nested “for” loop can also be used within the Bash code in a single line. So, we have updated the same Bash file after opening it within the nano editor as below. For the first “for” loop, we have used the values x, y, and z. ...
you can do that. So, we have decided to create one example for such a type of one-line while loop. Thus, I started the Bash file within the nano editor and added the Bash support at the first line. After that, we have initialized an integer value “i” with 2. At the following ...
for((i=1;i<10;i+=2)) do echo "Welcome $i times" done # For statement in one line for((i=1;i<=10;i+=2)); do echo "Welcome $i times"; done 如何建立一个字符串数组,并且查看每一个字符串? #!/bin/bash declare -a flush_results ...
for i in {0..20..5} do 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 ...
. Let's compare this with a cleaner, better structured, modern lookingforloop: for ((i=1;i<=5;i++)); do echo $i; done ✕Remove Ads This simpleforbased Bash one-liner (a term often used in Linux/Bash circles to conceptualize a mini-script written on a single line) will print ...
You can accomplish that by iterating a second list based on your first list through nested loops. This gets a little hard to follow when you're doing it as a one-liner, but it can definitely be done. Your nestedforloop gets executed on every iteration of the parentforloop. Be sure to...
