将某个目录下的文件合并成一行，中间用冒号（:）作为分隔符

1、paste

ls lib | sed 's@^@lib/@g' | paste -s -d ":"

2、 tr

ls lib | sed 's@^@lib/@g' | tr "n" ":" | sed 's@:$@@'

3、xargs

ls lib | sed 's@^@lib/@g' | xargs | sed 's/ /:/g'

4、awk

ls lib | sed 's@^@lib/@g' | awk "{if(NR%`ls lib | sed 's@^@lib/@g' | wc -l`){ORS=":"}else{ORS="n"};print;}"

5、perl

ls lib | sed 's@^@lib/@g' | perl -pe 's/n/:/;' | sed 's@:$@@'

6、python

#!/usr/bin/env python

#coding:utf8

import os

def dirList(dir):

filelist = os.listdir(dir)

allfile=[]

for filename in filelist:

allfile.append(dir+'/'+filename)

return allfile

allfile=dirList('lib')

pathjar=':'.join(allfile)

print pathjar
