#!/bin/bash

_subtitles_getSubtitlesForUrl() {
    local awkCode2=

    read -r -d "" awkCode2 << 'SEARCHFORIDSAWKEOF'

_subtitles_getSubtitlesForUrl

Answer 1

操作中显示（即“移动”一个块）。

键入捕获变量中的

time

数据，然后在匹配

napiprojekt:

：

时生成输出

td align=\"center\"><p>0进行这两组更改后，代码生成：2

# replace this:

time = substr($0, RSTART + 22, RLENGTH - 16)

# with this:

printf("%7s | fps: %6s |%10s | %s\n",substr($0, RSTART + 22, RLENGTH - 16) ,fps ,fileSize , napi_data)

#########
# replace this:

printf("%7s | fps: %6s |%10s | %s\n",time ,fps ,fileSize , substr($0, RSTART + 6, RLENGTH - 7))

# with this:

napi_data = substr($0, RSTART + 6, RLENGTH - 7)
