问题：

将如下形式文本

Name: John Doe1
address : somewhere
phone: 123-123-1234Name: John Doe2
address : somewhere
phone: 123-123-1233Name: John Doe3
address : somewhere
phone: 123-123-1232

转换成如下形式

Name: John Doe1                address : somewhere          phone: 123-123-1234
Name: John Doe2                address : somewhere          phone: 123-123-1233
Name: John Doe3                address : somewhere          phone: 123-123-1232

解法1：awk

awk 'BEGIN { FS="\n"; RS=""; OFS="\t\t" } { print $1, $2, $3 }' file.txt

解法2：sed

cat input.txt | sed '/^$/d' | sed 'N; s:\n:\t\t:; N; s:\n:\t\t:' 

cat input.txt | sed '/^$/d' | sed 'N; N; s:\n:\t\t:g' 

解法3：python

#!/usr/bin/env pythondef parse(inputfile, outputfile):dictInfo = {'Name':None, 'address':None, 'phone':None}for line in inputfile:if line.startswith('Name'):dictInfo['Name'] = line.split(':')[1].strip()elif line.startswith('address'):dictInfo['address'] = line.split(':')[1].strip()elif line.startswith('phone'):dictInfo['phone'] = line.split(':')[1].strip()s = 'Name: '+dictInfo['Name']+'\t'+'address: '+dictInfo['address'] \+'\t'+'phone: '+dictInfo['phone']+'\n'outputfile.write(s)if __name__ == '__main__':with open('output.txt', 'w') as outputfile:with open('infomation.txt') as inputfile:parse(inputfile, outputfile)

解法4 （paste）

chenqi@chenqi-OptiPlex-760:~/mypro/python/file-parsing$ paste -s -d'\t\t\t\n' infomation.txt
Name: John Doe1 address : somewhere phone: 123-123-1234
Name: John Doe2 address : somewhere phone: 123-123-1233
Name: John Doe3 address : somewhere phone: 123-123-1232
