I want to get a string between two special characters. For example,
/home/oracle/ggs/text.ext
I want oracle/ggs in the above string.
How can I do this using bash?

$ expr /home/oracle/ggs/text.ext : '/home/\(.*\)/'
oracle/ggs
That returns the part after /home/ and before the last /.
Other possible approaches that will fulfil your requirements:
$ echo /home/oracle/ggs/text.ext | cut -d/ -f3,4
oracle/ggs
$ echo /home/oracle/ggs/text.ext | cut -c 7-16
oracle/ggs
$ echo oracle/ggs
oracle/ggs

I got what I need thanks. >mysql_str=/home/oracle/ext/ggs/text.ext > path_str=
echo ${mysql_str}| cut -f 2 -d '/'> expr ${mysql_str} : '/'${path_str}'/(.*)/' oracle/ext/ggs > echo $path_str home– BOBJun 11, 2014 at 20:38
For this particular example, you can use awk:
echo "$string" | awk -F '/' '{printf "%s%s%s\n" ,$2,FS,$3}'
The same in Perl:
echo "$string" | perl -lanF '/' -E '$,="/";say @F[1,2]'

@StéphaneChazelas Can you please explain why the quotes are needed here? Won't
echobe happy with any number of arguments? Jun 11, 2014 at 20:23 -
1Leaving a variable unquoted in list context is the split+glob operator (the variable is split into words and each word is subject to globbing), that's independent of
echo. Try withstring='* *'for instance. Or withstring=/home/oracle/ggs/text.extwhere IFS is/. Jun 11, 2014 at 20:25
Bash
IFS=/ read -ra a <<<'/home/oracle/ggs/text.ext' &&
(IFS=/; printf '%s\n' "${a[*]:2:2}")
oracle/ggs
echo oracle/ggswill answer your question. Please clarify what the requirement are. Is that characters 7 to 16? From the 2nd to 4th/?&%asdf$Chris$fdsa?#for "the string between the$" would clearly mean that the result isChrisand, as visible, there is no other$sign in between. How else could the parser decide?? -- This question ought to be flagged as "too specific" as the technique described in the answers may not be needed elsewhere but in this lone case.
