Substituting with value of variable in Sed
Hi,
I have a program in which i have to substitute a TAG in a file with the value of a variable.
Code Snippet:
----------------
myvar=1234
sed 's/_TAG_/$myvar/' infile outfile
When I run this command, the _TAG_ in the "infile" is substituted with "$myvar" but NOT the value "1234" as desired by me.
Is there anyway to do it??
Thanks,
Jyoti

Hi all
I have a script as follows :-
#!/usr/bin/ksh
IDT=`date +"%OH%M%S"`
while true
do
echo ${IDT}
sleep 1
done
I need the time to show me the current runtime value for the time, however this returns the time as at the start of the script.
Any ideas.
Thanks

make_sockdfr
MAKE_SOCKDFR(8) System Manager's Manual MAKE_SOCKDFR(8)
NAME
make_sockdfr - Generates frozen route file for SOCKS server
SYNOPSIS
make_sockdfr [infile [outfile] ]
DESCRIPTION
make_sockdfr reads in a plain-text route file for the SOCKS server and produces a frozen route file as the output.
Both arguments are optional. The default for infile is /etc/sockd.route; the default for outfile is /etc/sockd.fr. You may specify infile
while omitting outfile, but you cannot specify outfile without also speficying infile.
The contents of the frozen route file is essentially the memory image of the parsed input file. Using the frozen route file can reduce the
start-up delay of the SOCKS server program since it no longer has to parse the file contents.
When the SOCKS server starts, it always looks for the frozen route file /etc/sockd.fr first. If that file is not found, it then tries to
use the plain-text route file /etc/sockd.route. If you use frozen route file, you must remember to run make_sockdfr every time after you
modify the plain-text file or the SOCKS server will continue to use the frozen version of a previous route file.
To find out the contents of a frozen route file, use dump_sockdfr.
FILES
/etc/sockd.fr, /etc/sockd.route
SEE ALSO
dump_sockdfr(8), sockd.fr(5), sockd.route(5)
