当我试图阻止通配符扩展到以下脚本时,它不起作用。例如,在shell中,我键入:(我还尝试过\*.m,“*.m”)

$ getLargeNumFiles.sh $(pwd) '*.m'

我得到了
$ myDirectory
$ file1.m file2.m file3.m
$ find: paths must precede expression
$ Usage: find [-H] [-L] [-P] [path...] [expression]
$ 0 #The result of my function. Found 0 .m files. Should be 3.

getLargeNumFiles.sh网站
#!/bin/bash
# Syntax
# getLargeNumFiles [folderPath][ext]
# [folderPath] The path of the folder to read.
#   To use at folder to search: $(pwd)

function largeRead()
{
    numFiles=0
    while read line1; do
        #echo $line1
        ((numFiles++))
    done
    echo $numFiles
}
folderPath=$1
ext=$2

echo $folderPath
echo $ext

find $folderPath -name $ext | largeRead

最佳答案

将变量放在引号中,以防止变量展开后通配符展开:

find "$folderPath" -name "$ext" | largeRead
