Wrap a string in tags using text manipulation in a Unix environment

I have a text file that outputs as below:

    /usr/local/jack/var/12345/configs/10.254.254.254
    1845:    edit "n_10.73.6.0/24"
    1847:        set subnet 10.73.6.0 255.255.255.0
    2161:        set member "n_10.73.8.0/24" "n_10.73.1.0/24" "n_10.73.2.0/24" "n_10.73.3.0/24" "n_10.73.4.0/24" "n_10.73.5.0/24" "n_10.73.6.0/24" "n_10.73.7.0/24" "n_10.73.9.0/24"
    7030:        set dst 10.73.6.0 255.255.255.0

    /usr/local/jack/var/12346/configs/10.254.254.255
    1845:    edit "n_10.73.6.0/24"
    1847:        set subnet 10.73.6.0 255.255.255.0
    2161:        set member "n_10.73.8.0/24" "n_10.73.1.0/24" "n_10.73.2.0/24" "n_10.73.3.0/24" "n_10.73.4.0/24" "n_10.73.5.0/24" "n_10.73.6.0/24" "n_10.73.7.0/24" "n_10.73.9.0/24"
    7030:        set dst 10.73.6.0 255.255.255.0

I want to be able to turn the file path into a hyperlink based on the file path itself. For example:

/usr/local/jack/var/12346/configs/10.254.254.255

would become:

<a href="http://jack.localnet/viewvc/12345/configs/10.254.254.255?view=markup">/usr/local/jack/var/12346/configs/10.254.254.255</a>

There could be 1,2 or hundreds of occurrences within this file. I want to make it so each occurrence will be replaced with a hyperlink.

Is this something that is possible with bash, sed, awk, python or similar?

Solution

sed 's,^\(/usr/local/jack/var/[0-9]*\)\(/.*\)$,<a href="http://jack.localnet/viewvc/12345\2?view=markup">\1\2</a>,g' file.txt

add -i if you want to replace the content of the file directly (but you need to be sure that the command is working fine). Safer, you can do :

sed 's,^\(/usr/local/jack/var/[0-9]*\)\(/.*\)$,<a href="http://jack.localnet/viewvc/12345\2?view=markup">\1\2</a>,g' file.txt > new_file.txt

Result :

<a href="http://jack.localnet/viewvc/12345/configs/10.254.254.254?view=markup">/usr/local/jack/var/12345/configs/10.254.254.254</a>
1845:    edit "n_10.73.6.0/24"
1847:        set subnet 10.73.6.0 255.255.255.0
2161:        set member "n_10.73.8.0/24" "n_10.73.1.0/24" "n_10.73.2.0/24" "n_10.73.3.0/24" "n_10.73.4.0/24" "n_10.73.5.0/24" "n_10.73.6.0/24" "n_10.73.7.0/24" "n_10.73.9.0/24"
7030:        set dst 10.73.6.0 255.255.255.0

7030:        set dst 10.73.6.0 255.255.255.0

is it normal if 12346 becomes 12345 ?
