If, by block, you mean not let them run you can try:
Then use sudo and /etc/sudoers to grant access to those processes that need it.
This is NOT a great idea. Period. Why do you want to block perl? Sounds like a manager decided this would solve a problem. It will create a lot of them as well, depending on what software you run.
Note =- /usr/bin/perl may not be where the perl executable lives. Change the above to match your system.
OK so I've inherited a set of scripts that do some work on a database. They do all have a standard comment block at the beginning that has good information on the script.

I was reading a book on UNIX internals "The design of the UNIX Operating system." There are two memory structures that are confusing me:
1) Buffer cache
2) Inode cache
My questions are
1) Does a process get both buffer cache and Indoe cache allocated when it opens/creates a file?
2) if no,... (1 Reply)

gzexe
GZEXE(1) General Commands Manual GZEXE(1)NAME
gzexe - compress executable files in place
SYNOPSIS
gzexe name ...
DESCRIPTION
The gzexe utility allows you to compress executables in place and have them automatically uncompress and execute when you run them (at a
penalty in performance). For example if you execute ``gzexe /usr/bin/gdb'' it will create the following two files:
-rwxr-xr-x 1 root root 1026675 Jun 7 13:53 /usr/bin/gdb
-rwxr-xr-x 1 root root 2304524 May 30 13:02 /usr/bin/gdb~
/usr/bin/gdb~ is the original file and /usr/bin/gdb is the self-uncompressing executable file. You can remove /usr/bin/gdb~ once you are
sure that /usr/bin/gdb works properly.
This utility is most useful on systems with very small disks.
OPTIONS -d Decompress the given executables instead of compressing them.
SEE ALSO gzip(1), znew(1), zmore(1), zcmp(1), zforce(1)CAVEATS
The compressed executable is a shell script. This may create some security holes. In particular, the compressed executable relies on the
PATH environment variable to find gzip and some standard utilities (basename, chmod, ln, mkdir, mktemp, rm, sleep, and tail).
BUGS
gzexe attempts to retain the original file attributes on the compressed executable, but you may have to fix them manually in some cases,
using chmod or chown.
