排序-n一個bash空間的內容分割的項目陣列

Question

我有這樣的結構::

. 
├── b withe spaces.py 
├── c.py 
├── lib.py 
├── show.sh 
└── sub 
    └── a.py 

我想這個結果::

$ bash ./show.sh 
    9 lines c.py    => info from outside script 
    17 lines a.py    => info from outside script 
    300 lines b withe spaces.py => info from outside script 
1589 lines lib.py   => info from outside script 
1915 lines total    => info from outside script 

這很容易通過wc -l排序::

$ wc -l *.py */*.py | sort -n 
    9 c.py 
    17 sub/a.py 
    300 b withe spaces.py 
1589 lib.py 
1915 total 

所以我的出發點是::

array=(
$(find ./ -name "*.py" -print0 | while read -d $'\0' file 
    do 
    llines=$(cat $file | wc -l) 
    analyse='ouput analyse from some script' 
    printf "%s =\t%25s => %s" $llines $file $analyse 
    done 
)) 

for item in ${array[@]}; do echo $item; done| sort -n 

Answer 1

你不需要的陣列全天：

find ./ -name "*.py" -print0 | while read -d $'\0' file ; do 
    llines=$(wc -l < "$file") 
    analyse='ouput analyse from some script' 
    # ----- you missed quoting these ---->vvv 
    printf "%s =\t%s => %s\n" "$llines" "$file" "$analyse" 
done | sort -k1nr 

Answer 2

你可以這樣做更容易：

find . -name "*sh" -print0 | wc --files0-from=- -l | sort -n | sed 's/\(^[0-9]\+\) \(.*\)/\1 lines \2 => info from outside script/' 

在這種情況下，你不會爲每個文件執行wc分開，這將節省時間有點。 另外wc會計算你的總數。
