You can split this string first by comma, then further split each element by pipe. echo "ID:001|Internet:Active,ID:002|TV:Inactive,ID:003|Phone:Active" | awk 'BEGIN {FS=","} {split($0, services, FS); for (service in services) {split(services[service], details, "|"); print deta...
1.length(string):返回字符串的长度 2.index(string,search_string):返回search_string在字符串中出现的位置 3.substr(string,start_pos,end-pos):在字符串中从start-pos开始到end-pos位置,生成子串 4.split(string,array,delimiter):用delimiter生成一个字符串列表,并将该列表存入数组,delimiter默认使用当前FS值。
跟java里的split函数的用法是很相像的,举例如下: Theawkfunctionsplit(s,a,sep) splits a stringsinto anawkarrayausing the delimitersep. set time = 12:34:56 set hr = `echo $time | awk '{split($0,a,":" ); print a[1]}'` # = 12 set sec = `echo $time | awk '{split($0,a,":...
The question is about splitting a string that contains the substring "1$$$" using awk. The attempts to split it with awk have failed. One solution is to use the escape character "\$" so that it is interpreted as a plain "$" by the shell and awk. Another solution involves setting up...
split_2 对于方法一,将系统IFS临时替换为分隔符,然后再换回去,达到分割字符串为数组的目的 对于方法二,采用awk的split函数分割,注意awk中的数组为关联数组,不清楚的同学们请查阅相关资料。
Get String Length First, let’s start with a basic usage of thelengthfunction inawk. Consider you have a text file,sample.txt. Each line is a record in the context ofawk. Here’s a simple command to get the length of each line: ...

When you use quotes, you’re often trying to create a literal, a string that you want the shell to pass to the command line untouched. In addition to the $ in the example that you just saw, other similar circumstances include when you want to pass a * character to a command such as...
AWK processes your data one record at a time. The record separator is the delimiter used to split the input data stream into records. By default, this is the newline character. So if you do not change it, a record is one line of the input file. NR –The current input record number...
