Nope, that's an incorrect statement. The correct statement is:

"I love yahoo" becomes "I love yah" because "o" appears in "yahoo" twice, and hence (both occurrences are) removed.

so "I am tech savvy" should become " I am tech savy"

Going by the stated requirement in your first post:

Quote:
...
I am tryung to use shell or perl to remove duplicate characters
...
and noting that the only duplicate characters in "I am tech savvy" are the two "v"s in "savvy", they should be removed, thus resulting in "I am tech say".

UPDATE-METAINIT(1)					User Contributed Perl Documentation					UPDATE-METAINIT(1)

NAME
update-metainit - Generates init scripts SYNOPSIS
update-metainit [--remove initname [--purge] ] DESCRIPTION
Metainit solves the problem of writing good init scripts. Instead of manually creating these important files, they are derived from a declaritive description in the metainit files in /etc/metainit. These files can be shipped with packages or created by the local adminis- trator. If update-metainit called without argument, it will regenerate init scripts for all the files in /etc/metainit. The generated files contain a large warning in form of a comment that they will be overridden. Modifications are preferably done in the files in /etc/metainit and made effective by running update-metainit. If needed, the administrator can prevent modified init files by removing the warning comment. OPTIONS
--remove initname This command will remove any generated and non-modified scripts that were created by the metainit file with the name initname. --purge Only usable with --remove. Will remove the generated files even if modified. SEE ALSO
