我有这个结果:

我只想要这样的一行:-)

这怎么可能?
我已经开始这样的脚本,但我认为我应该使用 awk、cut 等。
host=x.x.x.x
log=/data/div/sh/iperf.log
logr=reverseiperf.log
runs=2
for run in $(seq 1 $runs); do
date >> $log && iperf3 -c $host >> $log
done
答案1
这不是最简单的方法,但希望向您展示“一种方法”:
$ printf "%s%s\n" \
"$(TZ=CEST date -d "$(head -1 iperf.txt)" "+%y-%m-%d %H:%M:%S")" \
"$(grep sender iperf.txt | awk -F"] " '{print $2}')"
18-08-15 19:35:11 0.00-10.00 sec 3.60 GBytes 3.09 Gbits/sec 1467 sender
其工作原理如下:
printf "%s%s\n"
iperf.txt
- 打印我们将从您的输出中解析的 2 个字符串"$(TZ=CEST date -d "$(head -1 iperf.txt)" "+%y-%m-%d %H:%M:%S")"
iperf.txt
- 解析( )中的第一行head -1
并将其传递给date
命令,并按照示例所示的格式重新格式化日期"$(grep sender iperf.txt | awk -F"] " '{print $2}')"
- 解析包含字符串的行sender
,然后在字符上分割该行,打印分割的参数]
的右侧。]
这个结果就是$2
