有Google Voice API吗？(Is there a Google Voice API? [closed])

 要过滤掉重复的内容，请通过输出和管道： sort | uniq sort | uniq 从而： 
 
svn log --quiet | grep "^r" | awk '{print $3}' | sort | uniq
 
 如果这是你所要求的方式，我不会感到惊讶。 Unix工具通常期望用户使用其他工具进行花式处理和分析。 
 
 PS来想想，可以合并grep和awk ... 
 
svn log --quiet | awk '/^r/ {print $3}' | sort | uniq
 
 每位Kevin Reid 
 
svn log --quiet | awk '/^r/ {print $3}' | sort -u
 
 P 3 。 per kan，使用垂直条而不是空格作为字段分隔符，以正确处理带有空格的名称（也更新了Python示例）... 
 
svn log --quiet | awk -F ' \\\\|' '/^r/ {print $2}' | sort -u
 
 为了更有效率，您可以使用Perl一线。 我不太了解Perl，所以我会在Python中做这个事情： 
 
#!/usr/bin/env python
import sys
authors = set()
for line in sys.stdin:
    if line[0] == 'r':
        authors.add(line.split('|')[1].strip())
for author in sorted(authors):
    print(author)
 
 或者，如果你想要的话： 
 
#!/usr/bin/env python
from __future__ import print_function # Python 2.6/2.7
import sys
authors = {}
for line in sys.stdin:
    if line[0] != 'r':
        continue
    author = line.split('|')[1].strip()
    authors.setdefault(author, 0)
    authors[author] += 1
for author in sorted(authors):
    print(author, authors[author])
 
 然后你会跑： 
 
svn log --quiet | ./authorfilter.py

To filter out duplicates, take your output and pipe through: sort | uniq. Thus:
 
svn log --quiet | grep "^r" | awk '{print $3}' | sort | uniq
 
I woud not be surprised if this is the way to do what you ask. Unix tools often expect the user to do fancy processing and analysis with other tools.
 
P.S. Come to think of it, you can merge the grep and awk...
 
svn log --quiet | awk '/^r/ {print $3}' | sort | uniq
 
P.P.S. Per Kevin Reid...
 
svn log --quiet | awk '/^r/ {print $3}' | sort -u
 
P3.S. Per kan, using the vertical bars instead of spaces as field separators, to properly handle names with spaces (also updated the Python examples)...
 
svn log --quiet | awk -F ' \\\\|' '/^r/ {print $2}' | sort -u
 
For more efficient, you could do a Perl one-liner. I don't know Perl that well, so I'd wind up doing it in Python:
 
#!/usr/bin/env python
import sys
authors = set()
for line in sys.stdin:
    if line[0] == 'r':
        authors.add(line.split('|')[1].strip())
for author in sorted(authors):
    print(author)
 
Or, if you wanted counts:
 
#!/usr/bin/env python
from __future__ import print_function # Python 2.6/2.7
import sys
authors = {}
for line in sys.stdin:
    if line[0] != 'r':
        continue
    author = line.split('|')[1].strip()
    authors.setdefault(author, 0)
    authors[author] += 1
for author in sorted(authors):
    print(author, authors[author])
 
Then you'd run:
 
svn log --quiet | ./authorfilter.py
