[英]use awk variable in bash script
I have a txt file with blow format:我有一个吹格式的txt文件:
66.57.21 - john
88.43.23 - albert
10.10.11 - smith
I wanna to execute "connect.py 66.57.21 john" for each line and I wrote this bash script:我想为每一行执行“connect.py 66.57.21 john”,我写了这个 bash 脚本:
#!/bin/bash
while read LINE; do
awk -v number = "$LINE" '$1'
awk -v name = "$LINE" '$3'
connect.py $name $number
done < "$1"
but the bash script didn't work但是 bash 脚本不起作用
What is the problem问题是什么
#!/usr/bin/env bash
while read -r number _ name; do
connect.py "$name" "$number"
done < "$1"
If you are wanting to use awk, here is one way to do it:如果您想使用 awk,这是一种方法:
#!/bin/bash
while read LINE; do
number=$(echo $LINE | awk -F" " '{print $1}')
name=$(echo $LINE | awk -F" " '{print $3}')
connect.py $name $number
done < "${1:-/dev/stdin}"
here is the usage这是用法
cat input.txt | ./program.sh
