Freesco add-ons

Default Freesco package comes without GNU grep and find. Existing grep is just a hard-link to a general script, 'a:' (that's it, just an a and a colon).

% # in my case, 36 is the inode number for 'a:'
% gnu_find * -printf "%i %p\n" | grep ^"36 " | awk '{print $2}'
a: backup basename clr cp-rf crontab dir dirname edit free fromdos grep hostname installpkg listpkg ll lsmod minicom netinfo passwd play ps removepkg report sysedit sysinfo telnet todos uname uptime useradd userdel useredit userlist utils

[Linux] gnu_find /bin/ -printf "%i %p\n" | grep grep$

[Linux] more /bin/grep
#!/bin/sh
#
# Don't touch next lines. This script provides:
#@@ dir edit telnet lsmod clr a: userlist ll
#@@ basename dirname hostname passwd sysinfo report
#@@ sysedit free grep ps minicom useradd useredit
#@@ userdel netinfo uptime backup uname fromdos todos
#@@ cp-rf crontab play listpkg installpkg removepkg

You can see the basic grep part in blue. If you have installed bash (I hate the default ile command-line) you can play around:

[Linux] alias g=/pkg/bin/grep
[Linux] g a --version
grep (GNU grep) 2.3

[Linux] echo $?
0

If the result of 'g' is zero, you have GNU grep available.

[Linux] PKG=""
[Linux] $PKG/bin/grep a --version
sed: can't open --version
[Linux] [ $? != 0 ] && echo "You are using sed-grep"
You are using sed-grep

In the example above, you can see and proove the default usage of grep in Freesco.
