"ls -alh" 在不牺牲颜色和链接的情况下打印文件夹大小

Question

这是我找到的答案，显示 ls 大小 folder/file

(du -sh ./*; ls -lh --color=no) | awk '{ if( == "total") {X = 1}
else if (!X) {SIZES[] = } else { sub( "[ ]*", sprintf("%-7s ",
SIZES["./" ]), [=11=]); print [=11=]} }'

却失去了ls颜色的凉爽。如果你输入 --color=always 那么大小就会丢失。如何在上面的输出上有颜色？颜色必须与正常 ls -alh 输出相同

最后我写了一个脚本来打印输出和该脚本的别名。这就像变魔术一样。

alias le=~/bin/ls-ext.sh

确保 ~/bin 在你的路径中这是 ls-ext.sh 脚本

#!/bin/bash

PURPLE=$(tput setaf 5) GREEN=$(tput setaf 2) YELLOW=$(tput setaf 3) NC=$(tput sgr0)
let ln=0

pwd=;
if [ "${pwd::1}" = "." ] && [ ${#pwd} -eq 1 ]
then
        pwd=""
elif [ "${pwd: -1}" != "/" ] && [ ${#pwd} -gt 1 ]
then
        pwd="$pwd/"
fi

while read line
do
        ln=$((ln+1));   [ $ln -eq 1 ] &&        continue
        read -r -a array <<< "$line"
        duout=$(du -sh "$pwd${array[8]}" 2>/dev/null|cut -f1)
        [ $? -eq 0 ] && array[4]="$duout"
        if [ "${array[4]: -1}" = "G" ]
        then
                 array[4]="$PURPLE${array[4]}$NC"
        elif [ "${array[4]: -1}" = "M" ]
        then
                 array[4]="$YELLOW${array[4]}$NC"
        else
                 array[4]="$GREEN${array[4]}$NC"
        fi

        lsout="$(ls --color=always -d $pwd${array[8]})"
        if [ "${array[0]:0:1}" = "l" ]
        then
                read -r -a lsarray <<< "$(ls --color=always -lsd $pwd${array[8]})"
                lsout=$(echo "${lsarray[@]:9:${#lsarray[@]}}"|sed 's/[[:space:]]->[[:space:]]/->/')
        fi
        #echo -e "${array[@]::8} $lsout"
        printf "%-11s%3s %-10s%-10s%15s%4s%3s %-4s %s\n" ${array[0]} ${array[1]} ${array[2]} ${array[3]} ${array[4]} ${array[5]} ${array[6]} ${array[7]} $lsout
done  < <(ls -al --color=no $pwd )
echo "Total: $((ln-1))"

输出看起来像这样

"ls -alh" 在不牺牲颜色和链接的情况下打印文件夹大小

"ls -alh" to print folder sizes without sacrificing the color and links

linux

bash

awk

ls
