在awk中打​​印变量 [英] printing variable inside awk

问题描述

在此脚本中，我希望awk打印变量$file，$f，$order和sum/NR(均在单行中)

In this script , I want awk to print the variables $file, $f, $order and sum/NR (all in a single row)

#!/bin/bash
for file in pmb_mpi tau xhpl mpi_tile_io fftw ; do
    for f in 2.54 1.60 800 ;do
    if [ ${f} = 2.54 ]
    then 
        for order in even odd ; do
#       echo ${file}_${f}_${order}_v1.xls >> P-state-summary.xls
        awk '{sum+=$2} END {print ${file}_${f}_${order}_v1.xls, sum/NR}' ${file}_${f}_${order}_v1.xls >> P-state-summary.xls
        done
    else
#       echo ${file}_${f}_v1.xls >>  P-state-summary.xls
        awk '{sum+=$2} END {print  ${file}_${f}_v1.xls , sum/NR}' ${file}_${f}_v1.xls >>  P-state-summary.xls
    fi
    done
done

请问你们当中有人帮助我吗?

推荐答案

您可以执行以下操作:

echo -n "${file}_${f}_${order}_v1.xls " >> P-state-summary.xls
# or printf "${file}_${f}_${order}_v1.xls " >> P-state-summary.xls
awk '{sum+=$2} END {print sum/NR}' "${file}_${f}_${order}_v1.xls" | 
    tee "${file}_${f}_avrg.xls" >> P-state-summary.xls

使用不带\ n的echo -n或printf将输出不带换行符的文本，因此awk命令的输出将在同一行之后.我添加了一个空格作为分隔符，但您可以使用任何东西.

Using echo -n or printf without a "\n" will output the text without a newline so the output of the awk command will follow it on the same line. I added a space as a separator, but you could use anything.

使用tee将允许您使用每个输入(订单)文件一个调用awk的方式将输出写入单个文件和摘要文件.

Using tee will allow you to write your output to the individual files and the summary file using only one awk invocation per input (order) file.
