我正在寻找parsing一个空格分隔的input文本文件使用awk。 列代码对于每个组可以有多个行。 我将不胜感激任何帮助。
LOCATION SHANNON GROUP NUM SWITCH CODE HEX 0 4 OFF 1 3 1 13 ON 2 4 8 14 LOCATION LOUTH GROUP NUM SWITCH CODE HEX 0 1 OFF 1 4 1 2 ON 0 F 2 所需的输出文件
LOCATION GROUP NUM SWITCH CODE HEX SHANNON 0 4 OFF 1 3 SHANNON 1 13 ON 2 4 SHANNON 1 13 ON 8 4 SHANNON 1 13 ON 14 4 LOUTH 0 1 OFF 1 4 LOUTH 1 2 ON 0 F LOUTH 1 2 ON 2 F
#!/usr/bin/awk -f BEGIN { # You can customize this to change your output layout based on your preference. format = "%-10s%-7s%-5s%-8s%-5s%-3s\n" printf format, "LOCATION", "GROUP", "NUM", "SWITCH", "CODE", "HEX" } ++i==2{ l = $1 } i>4{ if (/^[[:blank:]]*$/) { i = 0 } else if (NF > 1) { printf format, l, $1, $2, $3, $4, $5 p1=$1; p2=$2; p3=$3; p5=$5 } else { printf format, l, p1, p2, p3, $1, p5 } }
运行：
awk -f script.awk file
输出：
LOCATION GROUP NUM SWITCH CODE HEX SHANNON 0 4 OFF 1 3 SHANNON 1 13 ON 2 4 SHANNON 1 13 ON 8 4 SHANNON 1 13 ON 14 4 LOUTH 0 1 OFF 1 4 LOUTH 1 2 ON 0 F LOUTH 1 2 ON 2 F
