This article focuses on "what are the methods of calculating string length in Shell scripts". Interested friends may wish to take a look. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn "what are the methods of calculating string length in Shell scripts?"

Method 1: use the wc-L command

Wc-L can get the length of the current line, so you can use this simple method to get the string of individual lines, and wc-l is the number of lines that get the contents of the current string.

The code is as follows:

Echo "abc" | wc-L

Method 2: expr length string

Use expr length to get the length of the string

Method 3: awk gets the number of fields, but if there is a problem if the length is greater than 10 characters, you need to confirm later.

The code is as follows:

Echo "abc" | awk-F ""'{print NF}'

Method 4: get the string length by awk+length

The code is as follows:

Echo "Alex" | awk'{print length ($0)}'

Method 5: through echo ${# string} (note: string here is the variable name of the string)

The code is as follows:

Name=Alex

Echo ${# name}

At this point, I believe you have a deeper understanding of "what are the methods of calculating string length in Shell scripts?" you might as well do it in practice. Here is the website, more related content can enter the relevant channels to inquire, follow us, continue to learn!
