有没有一种方法可以在一段时间内使用较少的命令？
我有一个循环进行输入并为每个条目创建一个printf。这个文件真的很大，因此打印出来将永远需要。有什么方法可以将结果保存到文件中，并使用少使其成为打页的输出？
while read line
do
id=$(cut -d' ' -f1 <<< $line)
ip=$(cut -d' ' -f2 <<< $line)
mon=$(cut -d' ' -f3 <<< $line)
day=$(cut -d' ' -f4 <<< $line)
printf "%s 45%s (%s %s)\n" "$id" "$ip" "$mon" "$day"
done <<< "$inputFile"
我尝试了此操作
result+=$("%s 45%s (%s %s)\n" "$id" "$ip" "$mon" "$day")
，然后只是
less "$result"
在循环外进行，但这不起作用，我不知道该从这里去哪里。
I have this while loop that takes an input and creates a printf for each entry. This file is really big so having it print out will take forever. Is there a way I can save the result to a file and use less to have it be a paginated output?
while read line
do
id=$(cut -d' ' -f1 <<< $line)
ip=$(cut -d' ' -f2 <<< $line)
mon=$(cut -d' ' -f3 <<< $line)
day=$(cut -d' ' -f4 <<< $line)
printf "%s 45%s (%s %s)\n" "$id" "$ip" "$mon" "$day"
done <<< "$inputFile"
I tried this
result+=$("%s 45%s (%s %s)\n" "$id" "$ip" "$mon" "$day")
and then just doing
less "$result"
outside the loop but that didn't work and I don't know where to go from here.

正如戈登所说，这是很多毫无意义的工作，尤其是如果文件将很大。也
＆lt;＆lt;＆lt; “ $ inputfile”表示您所说的文件的整个文本，已经读取了inputfile变量，除非有inputfile变量一些具体原因？尝试这样的事情 -
或者如果您希望将输出保存在文件中并分页到屏幕上，
我也同意Clint。分页可能应该是分开的 - 但是，由于我还没有看到整个结构，请尝试一些，看看什么有效。
As Gordon said, this is a lot of pointless work, especially if the file is going to be big. Also
<<< "$inputFile"implies the entire text of the file you said was so big has already been read into theinputFilevariable, which seems pointless and counterproductive unless there's some specific reason?Try something like this -
or if you want the output saved in a file AND paginated to the screen,
I also agree with Clint. The pagination should probably be separate - but since I haven't seen the whole structure, try a few and see what works.
