我想用grep搜索一个如下所示的字符串:

something ~* 'bla'

我试过这个,但是shell删除了单引号argh ..

grep -i '"something ~* '[:alnum:]'"' /var/log/syslog

什么是正确的搜索？

df=pd.DataFrame({"A":["one","two","three"],"B":["fopur","give","six"]})

当我做,

df.B.str.contains("six").any()
out[2]=True

当我做,

df.B.str.contains("six)").any()

我收到以下错误,

C:\ProgramData\Anaconda3\lib\sre_parse.py in parse(str, flags, pattern)
    868     if source.next is not None:
    869         assert source.next == ")"
--> 870         raise source.error("unbalanced parenthesis")
    871 
    872     if flags & SRE_FLAG_DEBUG:

error: unbalanced parenthesis at position 3

请帮忙!
