我正在学习在wget
函数中自定义bash
并遇到问题。我想显示Downloading (file):%
而不是wget
的混乱输出。下面的功能似乎很接近我无法根据我的特定需求调用它。
例如,我的标准wget
是:
cd 'C:\Users\cmccabe\Desktop\wget'
wget -O getCSV.txt http://xxx.xx.xxx.xxx/data/getCSV.csv
并将.csv作为.txt下载到指定目录中的所有凌乱的wget
输出。
这个功能似乎会或多或少地做我需要的功能,但我似乎无法使用我的数据正常运行。以下是我的尝试。谢谢你:)。
#!/bin/bash
download() {
local url=$1 wget -O getCSV.txt http://xxx.xx.xxx.xxx/data/getCSV.csv
local destin=$2 'C:\Users\cmccabe\Desktop\wget'
echo -n " "
if [ "$destin" ]; then
wget --progress=dot "$url" -O "$destin" 2>&1 | grep --line-buffered "%" | \
sed -u -e "s,\.,,g" | awk '{printf("\b\b\b\b%4s", $2)}'
else
wget --progress=dot "$url" 2>&1 | grep --line-buffered "%" | \
sed -u -e "s,\.,,g" | awk '{printf("\b\b\b\b%4s", $2)}'
fi
echo -ne "\b\b\b\b"
echo " DONE"
}
