问题


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

abc.pl

So when I do

$grep abc.pl * 

in that directory, it gives me following results

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)

When I tried

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

OR

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

its giving me

cut: invalid delimiter

When I read man for cut it states

delim can be a multi-byte character.

What am I doing/interpreting wrong here?

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

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):

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



回答2:


Try using this.

$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).




回答3:


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




回答4:


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

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




回答5:


Or you can try eg Ruby:

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