数据统计，还能更精简吗（以及其它语言）？

这是我写的网卡流量统计脚本，zsh+awk，太长了。谁来写个纯 shell 版、纯 awk 版、Perl / Ruby / Haskell 等语种的版本？
[bash]
#!/bin/zsh
zgrep -P 'pppd\[\d+\]: Sent' /var/log/everything.log*(Om) | cut -d: -f2- | awk '
function ceiling(x) {
return (x == int(x)) ? x : int(x)+1;
}
function toM(x) {
return x / 1024.0 / 1024.0;
}
{
a = toM($7);
b = toM($10);
printf("%s %s %s: %4.1fMiB sent, %4.1fMiB received.\n", $1, $2, $3, a, b);
s += $7; r += $10;
sm += ceiling(a); rm += ceiling(b);
}
END {
printf("Total by bytes: %4.1fMiB sent, %4.1fMiB received.\n", toM(s), toM(r));
printf("Total by MiB : %4.1fMiB sent, %4.1fMiB received.\n", sm, rm);
}
'
[/bash]
[bash]
#!/bin/zsh
zgrep -P 'pppd\[\d+\]: Sent' /var/log/everything.log*(Om) | cut -d: -f2- | awk '
function ceiling(x) {
return (x == int(x)) ? x : int(x)+1;
}
function toM(x) {
return x / 1024.0 / 1024.0;
}
{
a = toM($7);
b = toM($10);
printf("%s %s %s: %4.1fMiB sent, %4.1fMiB received.\n", $1, $2, $3, a, b);
s += $7; r += $10;
sm += ceiling(a); rm += ceiling(b);
}
END {
printf("Total by bytes: %4.1fMiB sent, %4.1fMiB received.\n", toM(s), toM(r));
printf("Total by MiB : %4.1fMiB sent, %4.1fMiB received.\n", sm, rm);
}
'
[/bash]
