查找和替換使用字典中的單詞在linux

Question

我需要使用的字典文件中的替換詞AAAA：

dictionary.txt

AXF1 
ZCFA 
ZCCC 

詞典約1500字。 我需要用AXF1替換AAAA，然後我需要找到下一個AAAA並用ZCFA替換... 任何想法我該怎麼做？我發現一切是如何取代像這樣：

AAA1:AXF1 
AAA2:ZCFA 
etc... 

Answer 1

喜歡的東西：

# Read dictionary into memory 
dictionary = [line.strip() for line in open('dictionary.txt')] 

# Assuming a bit of a wrap around may be required depending on num. of AAAA's 
from itertools import cycle 
cyclic_dictionary = cycle(dictionary) 

# Read main file 
other_file = open('filename').read() 

# Let's replace all the AAAA's 
import re 
re.sub('A{4}', lambda L: next(cyclic_dictionary), other_file, flags=re.MULTILINE) 

Answer 2

awk 'FNR == NR {list[c++] = $1; next} 
{ 
    while (sub("AAAA", list[n++])) { 
     n %= c 
    } 
    print 
}' list.txt inputfile.txt 

Answer 3

這可能會爲你工作（GNU SED）：

cat <<\! >dictionary.txt 
> AXF1 
> ZCFA 
> ZCCC 
> ! 
cat <<\! >file.txt 
> a 
> b 
> AAAA 
> c 
> AAAA 
> d 
> AAAA 
> ! 
sed -e '/AAAA/{R dictionary.txt' -e ';d}' file.txt 
a 
b 
AXF1 
c 
ZCFA 
d 
ZCCC
