BASH Shell 简易进度条小函数

不多说，直接上脚本。

# processbar <current> <total>

processbar() {

  local current=$1; local total=$2;

  local maxlen=80; local barlen=66; local perclen=14;

  local format="%-${barlen}s%$((maxlen-barlen))s"

  local perc="[$current/$total]"

  local progress=$((current*barlen/total))

  local prog=$(for i in `seq 0 $progress`; do printf '#'; done)

  printf "\r$format" $prog $perc

}

# Usage(Client)

for i in `seq 1 10`; do

  processbar $i 10

  sleep 1

done

echo ""
