Hi Unix community,

Please help me !! I want to write a shell programm that searches tree recursively and identifies all files for which the first line consists
of the Tag . The programm accepts a directory name on its command line and starts its search in that directory. When it invokes itself to start searching in a sub-directory, it must call itself $PROGHOME/a1shell.sh. When a HTML file is found, the perl programm is run by using the name $PROGHOME/a1perl.pl and is given the file's name, assuming it is in the current working directory. The testing system will export PROGHOME as an environment variable to the shell programm.
