Numerical Labeling using sed
Hi,

I have been working on this problem, but could only get so far. I have a file that looks like this

Code:
(cat,chimp,(((dog,cat,cow),orangutan),((horse,((cat,dog),(cow,pig))),cat,mouse,rat)));

I would like after each instance of the word 'cat' to have an incrementing numerical label.

I would like my end file to look like this

Code:
(cat1,chimp,(((dog,cat2,cow),orangutan),((horse,((cat3,dog),(cow,pig))),cat4,mouse,rat)));

so far i have tried this
Code:
sed -e 's/cat/cat#1/' -e 's/cat/cat#2/'  FileIn > Fileout

which places #1 & #2 after the first cat, and ignores the rest.

I then tried this
Code:
sed '
/cat/ a\
1
' FileIn> Fileout

which was even more useless as it just placed a 1 at the end of my string. If anyone has any suggestions or tips to put me in the right direction i would very much appreciate it.

Thank you

Code:
echo '(cat,chimp,(((dog,cat,cow),orangutan),((horse,((cat,dog),(cow,pig))),cat,mouse,rat)));' | nawk -F'cat' '{for(i=1;i<=NF;i++) printf("%s%s", $i, (i==NF)?ORS:FS i)}'

Perl One Liner to Count Occurence of String and append Count to string
If you want an ever-increasing count for the whole file.

Code:
perl -ple 's/(cat)/$1.++$i/eg' in > out

If you want the string count to reset after the end of each line:

Code:
perl -ple 's/(cat)/$1.++$i/eg; $i=0' in > out

Adding zero-width word boundaries will make sure you don't count the "cat" in strings like "category", or "altercation"

Code:
perl -ple 's/\b(cat)\b/$1.++$i/eg' in > out

Hope that Helps

Not as generic as awk, but this sed would work too:
Code:
sed 's/cat/&1/1;s/cat/&2/2;s/cat/&3/3;s/cat/&4/4'

or
Code:
sed -e 's/cat/&1/1' -e 's/cat/&2/2' -e 's/cat/&3/3' -e 's/cat/&4/4'

Numerical Labeling using sed
Dear All,

Thank you so much, i wasnt expecting so many replies on this. Really enjoyed the three different options here, awk, perl and sed.

Thanks again,
