是否可以在unix cut命令中使用字符串作为分隔符？

If I want to cut a list of text using a string as a delimiter, is that possible? For example I have a directory where a list of shell scripts call same perl script say

如果我想使用字符串作为分隔符来剪切文本列表,那可能吗?例如,我有一个目录,其中shell脚本列表调用相同的perl脚本说

abc.pl

So when I do

所以,当我这样做

$grep abc.pl *

in that directory, it gives me following results

在该目录中,它给了我以下结果

xyz.sh: abc.pl 1 2
xyz2.sh: abc.pl 2
mno.sh: abc.pl 3
pqr.sh: abc.pl 4 5

I basically want all the output after "abc.pl" (to check what range arguments are being passed to the perl right now)

我基本上想要“abc.pl”之后的所有输出(以检查现在传递给perl的范围参数)

When I tried

当我尝试

$grep abc.pl * | cut -d'abc.pl' -f2

$grep abc.pl * | cut -d'abc\.pl' -f2

its giving me

它给了我

cut: invalid delimiter

When I read man for cut it states

当我读人为切,它说

delim can be a multi-byte character.

delim可以是多字节字符。

What am I doing/interpreting wrong here?

我在做什么/解释错了?

5 个解决方案

#1

When I read man for cut it states ... delim can be a multi-byte character.

当我读到man for cut时,它表示... delim可以是一个多字节字符。

Multi-byte, but just one character, not a string.

多字节,但只是一个字符,而不是字符串。

canti:~$ ll | cut --delimiter="delim" -f 1,2
cut: the delimiter must be a single character
Try `cut --help' for more information.

canti:~$ cut --version  
cut (GNU coreutils) 5.97

You can specify only output delimiter as a string (useless in this case):

您只能将输出分隔符指定为字符串(在本例中无用):

 --output-delimiter=STRING                                                          
        use STRING as the output delimiter the default is to use the input delimiter

#2

why not use grep abc.pl | awk '{print $3, $4}'?

为什么不使用grep abc.pl | awk'{print $ 3,$ 4}'?

#3

Try using this.

试试这个。

$grep abc.pl * | awk -F 'abc.pl' '{print $2}'

-F fs --field-separator fs Use fs for the input field separator (the value of the FS predefined variable).

-F fs --field-separator fs将fs用于输入字段分隔符(FS预定义变量的值)。

#4

$ grep abc.pl * | cut -d' ' -f3-999

$ grep abc.pl * | cut -d'' - f3-999

In that case just use the space character as the delimiter.

在这种情况下,只需使用空格字符作为分隔符。

#5

Or you can try eg Ruby:

或者你可以尝试例如Ruby:

grep abc.pl * | ruby -ne 'p $_.chomp.split("abc.pl").last'
