sed -e 's/${line1}/${line1_m}/g' prod_hier_1234.txt > test.txt
It doesn't do the job of replacing the string stored in variable 'line1' to 'line1_m'.

However If I replace the line as below(by replacing the actual string)
sed -e 's/A,P,CMD,20-SEP-06,2006/A,P,CMD,20-SEP-06,20062814/g' prod_hier_1234.txt>test.txt
it works..

Could someone provide thougs about what could be the problem and the possible solution?

Thanks,
Bhagat
Hi,

I haven't tested it but don'y you have to double quote your sed scripting instead of single when using variables?
sed -e "s/${line1}/${line1_m}/g" prod_hier_1234.txt > test.txt

x2sys_merge

X2SYS_MERGE(1gmt)					       Generic Mapping Tools						 X2SYS_MERGE(1gmt)

NAME

       x2sys_merge - Merge an updated COEs tables

SYNOPSIS

       x2sys_merge -Amain_COElist.d -Mnew_COElist.d

DESCRIPTION

       x2sys_merge  will read two crossovers data base and output the contents of the main one updated with the COEs in the second one. The second
       file should only contain updated COEs relatively to the first one.  That is, it MUST NOT contain any new  two  tracks  intersections  (This
       point  is  NOT checked in the code). This program is useful when, for any good reason like file editing NAV correction or whatever, one had
       to recompute only the COEs between the edited files and the rest of the database.

       -A     Specify the file main_COElist.d with the main crossover error data base.

       -M     Specify the file new_COElist.d with the newly computed crossover error data base.

OPTIONS

       No space between the option flag and the associated arguments.

       EXAMPLES
	      To update the main COE_data.txt with the new COEs estimations saved in the smaller COE_fresh.txt, try

	      x2sys_merge -ACOE_data.txt -MCOE_fresh.txt > COE_updated.txt
