search and truncate help

shirt · 03-16-2012, 02:50 AM

I need somehelp on the sed command. the file contains the following information.
((type = file)
(method = DIRECTORY = /usr/local/bin))

I tried with the following command but the output is different then running the multiple commands individually.
sed -ne "/DIRECTORY/p" -ne "s/^[^=]\+=//p" tmp.txt
Output:
file)
(method = DIRECTORY = /usr/local/bin))
DIRECTORY = /usr/local/bin)))

but i am trying for the result "/usr/local/bin". Another information to note here is that the /usr/local/bin path will differ each time, the output should be path in between = and ). Any help or direction for the result would be helpful.

Thanks for your help in advance.

What about this?

Code:

sed -rn '/DIRECTORY/s:.*= ([^)]+).*:\1:p' tmp.txt

Hi,

It is not entirely clear if you want the output to be just that one line (DIRECTORY = /usr/local/bin) or if the rest of the file needs to be shown as well (unchanged).

Only show specific, edited, line:

Code:

sed -n '/DIRECTORY/s/.*= \(.*\)\/.*/DIRECTORY = \1/p' tmp.txt

# output would be
DIRECTORY = /usr/local/bin

Show all, but change specific line:

Code:

sed '/DIRECTORY/s/.*= \(.*\)\/.*/DIRECTORY = \1/' tmp.txt

# output would be
((hello
(type = file)
DIRECTORY = /usr/local/bin

BTW: Please put your script/data inside [code] ... [/code] tags it preserves all spacing. If you don't know how: LQ - BB Code List.

Hope this helps.

EDIT: If the DIRECTORY = isn't wanted:

Code:

sed -n '/DIRECTORY/s/.*= \(.*\)\/.*/\1/p' tmp.txt

# output would be
/usr/local/bin

Hi.

Try this

Code:

$ sed -rn 's/.*DIRECTORY = ([^)]*)\).*/\1/p' infile.txt
/usr/local/bin/temp.txt
