@apmcd74:
Please notice that when you define a variable with:
you create an array, not a string. The parameter expansion ${cname/searchword/replacement} deals with strings though. i.e.
bakunin
My point was that you can do string manipulation per element, or for all elements in an array of strings, thus:
As I said, this works for bash and ksh93 on my Ubuntu systems; I haven't tried it out on ksh88.

I have a variable which consists of a string like this:
001 aaabc 44 a bbb12
How do I extract each substring, delimited by the spaces, into new variables - one for each substring?
eg var1 will be 001, var2 will be aaabc, var3 will be 44, var4 will be a, etc?
I've come up with this:... (2 Replies)

I want to echo $WHEREIAM in such a way that I get it back with all the environment variables resolved (/tmp/here/location/dev).
This command will be used in a shell script. (5 Replies)

if the script name is /some/where/path/script_name.ksh

In a bash script I've set a variable that is the directory name of where an executable lives.
the_dir=`dirname $which myscript`
which equates to something like "/path/to/dir/bin"
I need to cut that down to remove the "bin" so I now have "/path/to/dir/".
This sounds easy but as a... (2 Replies)

pydhcplib.strlist
pydhcplib.strlist(3) PYDHCPLIB pydhcplib.strlist(3)NAME
pydhcplib.strlist - Internal type of pydhcplib for lists of bytes processing.
SYNOPSIS
from pydhcplib.type_hw_addr import hwmac
a = strlist()
a = strlist([100,100,10,42,44,26])
DESCRIPTION
The class pydhcplib.strlist is an specific type of pydhcplib. It exist in order to simplify processing of raw data from network. When a
dhcp packet dhcp is received, it's a succession of approximately 300 bytes. Within pydhcplib these data are transformed in an intermediary
form of type "strlist" in order to facilitate their handling. This intermediary form will eventually be suppressed in the stable versions
of pydhcplib to speedup the processing time, but backward compatibility will be assured.
The pydhcplib.strlist class creation argument can be a list of numbers whose value goes from 0?55.
The pydhcplib.strlist class creation argument can be a string of ASCII character.
METHODS
The implemented methods in this type are mostly comparison methods (= =, >, etc...)
else :
str() convert the address into a printable string type.
list() convert the address into a list of bytes.
EXAMPLES
Example program strlist_example.py :
from pydhcplib.type_strlist import strlist
word = strlist()
word1 = strlist("azerty")
word2 = strlist("qwerty")
word3 = strlist([97, 122, 101, 114, 116, 121])
print "a0 : ",word
print "a1 : ",word1
print "a2 : ",word2
print "a3 : ",word3
if word1 == word2 :
print "test 1 : ",word1, "==",word2
else :
print "test 1 : " ,word1, "!=",word2
if word1 == word3 :
print "test 2 : ", word1, "==",word3
else :
print "test 2 : ", word1, "!=",word3
