I have a script that takes an option for server pools to run the script against. The option is given as a comma separated list (ie, -p 201,204,301).
I'm using eval and brace expansion to get those pool numbers into an array. It works fine unless only 1 pool number is given. Here's the code:

Hello,
is there a kind soul who can answer me, does the SH support double substitution known as indirect expansion similar to BASH? The syntax for bash is ${!var}.

VAR="value"
REF_VAR="VAR"
echo ${!REF_VAR}
and get the "value"... (1 Reply)

ns_zlib
ns_zlib(3aolserver) AOLserver Zlib Extension ns_zlib(3aolserver)__________________________________________________________________________________________________________________________________________________NAME
ns_zlib - Zlib compression support
SYNOPSIS
ns_zlib compress string
ns_zlib gunzip file
ns_zlib gzip string
ns_zlib gzipfile file
ns_zlib uncompress string
_________________________________________________________________DESCRIPTION
The ns_zlib command enables compressing and uncompressing of strings or files. The command is available if the nszlib.so module is loaded
into AOLserver or the libnszlib.so, nszlib.dll, or libnszlib.dylib dynamic library is loaded using the load command in a suitable tclsh
such as nstclsh.
ns_zlib compress string
This command compresses the given string and returns a Tcl byte array object with the compressed data.
ns_zlib gunzip file
This command uncompresses the contents of the given gzipped file and returns a string as the result.
ns_zlib gzipfile file
This command is similar to the gzip shell routines, compressing the given file into a new file with the .gz extension. If success-
ful, the original uncompressed file is deleted.
ns_zlib uncompress bytearray
This command takes a byte array object which includes compressed data and returns an uncompressed string object.
EXAMPLES
The following examples demonstrate compressing and uncompressing a string;
# Compress Tcl string
set test "This is test string"
set data [ns_zlib compress $test]
set test [ns_zlib uncompress $data]
--> returns "This is test string"
# Compress the string into gzip format
set gzip [ns_zlib gzip $test]
# Save as gzip file
set fd [open /tmp/test.gz w]
fconfigure $fd -translation binary -encoding binary
puts -nonewline $fd $gzip
close $fd
# Uncompress gzipped file
set test [ns_zlib gunzip /tmp/test.gz]
--> returns "This is test string"
