The Bash for loop To achieve a recursive loop through directories, we will use bash loops, specifically, a for a loop. The for loop is a common type of loop in Bash and other programming languages. It iterates over a given list of items/options until and executes a set of commands....
In our case, it cycles through the directories using the ‘*’ Wild card character. Syntax: Below is the syntax to loop through the directories. for f in /folder/* folder/**/* ; do instruction done; In this, we are using the for loop along with the “f” variable that will be ...
dirs=`ls "$1"` #echo "Dirs: $dirs" # Just to confirm if all is well IFS=$'\n' # Loop through and print for i in $dirs; do if [ -f "$i" ]; then echo "File: $i" elif [ -d "$i" ]; then echo "Directory: $i" fi done ...
5. Loop through files and directories in a for loop To loop through files and directories under a specific directory, just cd to that directory, and give * in the for loop as shown below. The following example will loop through all the files and directories under your home directory. $ c...
The "for" loop iterates through each file in the current directory using the wildcard *, which matches all files and directories. Within the loop, the script checks if each item is a regular file using the -f test operator. If the item is a regular file, its filename is printed to ...
For example, let us use the continue statement to iterate through a range of number and when it reaches a specific number, which in this case will be ‘4’, the continue statement will exit the iteration and go back to the beginning of the loop to begin the next iteration. for i in...
for Output in $(ls)do cat "$Output"done# while 循环：while [ true ]do echo "loop body here..." breakdone# 你也可以使用函数# 定义函数：function foo (){ echo "Arguments work just like script arguments: $@" echo "And: $1 $2..." echo "This is a function" ...
#This loop will go to each immediate child and execute dir_command find . -maxdepth 1 -type d \( ! -name . \) | while read dir; do dir_command"$dir/" done #This example loop only loops through give set of folders declare -a dirs=("dir1""dir2""dir3") ...
Loop through files or directories to automatically rename or change permissions for multiple elements at once. Command Substitution Theforloop accepts command substitution as a list of elements to iterate through. The next example demonstrates how to write aforloop with command substitution: ...
Additionally, we can include a value at the end of the range that is going to cause thefor loopto iterate through the values in incremental steps. The following bash script prints the values between 1 and 7 with 2 incremental steps between the values starting from the first value. ...
