Shell scripting sed Variable substituion problem
Hi All ,
I am setting variables as shown below
PHP Code:
setenv MODULE1 modem_1_3
setenv MODULE2 modem5_1_2
setenv MODULE3 modem5_1
setenv MODULE4 modem5_2_top_a
setenv COUNT 4
I am having another bash script as shown below
########################################################
HTML Code:
#!/bin/bash
for (( c=1; c<=${COUNT}; c++ ))
do
sed -n '/module '${MODULE}'${c} /,/endmodule/p' prescan.v > temp${c}.v
sed -i '0,/o_func_clk /s/o_func_clk/o_func_clk, DFT_ClkEnScanIn1 ,scan_clock_en , DFT_ClkgenScanEnable /' temp${c}.v
#sed -i '0,/i_UDR_DFT_free_running;/i_UDR_DFT_free_running;/i_UDR_DFT_free_running , DFT_ClkEnScanIn1 , DFT_ClkgenScanEnable ;/' temp${c}.v
sed -i 's/i_UDR_DFT_free_running;/i_UDR_DFT_free_running , DFT_ClkEnScanIn1 , DFT_ClkgenScanEnable ;/' temp${c}.v
sed -i '/\[0\:0\] i_func_clk_en/a output scan_clock_en ;' temp${c}.v
sed -i '/scan_clock_en_reg/,+1d' temp${c}.v
sed -i '/endmodule/i M8E35B_SDFF2X1 scan_clock_en_reg (.q ( scan_clock_en ) , .d (pre_scan_clock_en ) , .te ( DFT_ClkgenScanEnable ) , .ti ( DFT_ClkEnScanIn1 ) , .phi ( i_scan_clk ));' temp${c}.v
done
################################################################
This script should go in loop and create different files temp1.v temp2.v temp3.v and temp4.v
My problem is in the first line
sed -n '/module '${MODULE}'${c} /,/endmodule/p' prescan.v > temp${c}.v
variable substition is not happening and temp is not getting created
I tried with double quotes but then also its not working ...
Incrementing the $c in the loop and $Module1 or $Module2 like that should be read as defined in environment variable and substitution should happen but I am getting empty temp files
Please let me know how to tackle this issue ?

maxdb_stmt_result_metadata
MAXDB_STMT_RESULT_METADATA(3) 1 MAXDB_STMT_RESULT_METADATA(3)
maxdb_stmt_result_metadata - Returns result set metadata from a prepared statement
Procedural style
SYNOPSIS
resource maxdb_stmt_result_metadata (resource $stmt)
DESCRIPTION
Object oriented style
resource maxdb_stmt::result_metadata (void )
If a statement passed to maxdb_prepare(3) is one that produces a result set, maxdb_stmt_result_metadata(3) returns the result resource
that can be used to process the meta information such as total number of fields and individual field information.
Note
This result set pointer can be passed as an argument to any of the field-based functions that process result set metadata, such as:
omaxdb_num_fields(3)
omaxdb_fetch_field(3)
omaxdb_fetch_field_direct(3)
omaxdb_fetch_fields(3)
omaxdb_field_count(3)
omaxdb_field_seek(3)
omaxdb_field_tell(3)
omaxdb_free_result(3)
The result set structure should be freed when you are done with it, which you can do by passing it to maxdb_free_result(3)
Note
The result set returned by maxdb_stmt_result_metadata(3) contains only metadata. It does not contain any row results. The rows are
obtained by using the statement handle with maxdb_fetch(3).
RETURN VALUES
maxdb_stmt_result_metadata(3) returns a result resource or FALSE if an error occurred.
EXAMPLES
Example #1
Object oriented style
<?php
$maxdb = new maxdb("localhost", "MONA", "RED", "DEMODB");
$maxdb->query("CREATE TABLE temp.friends (id int, name varchar(20))");
$maxdb->query("INSERT INTO temp.friends VALUES (1,'Hartmut')");
$maxdb->query("INSERT INTO temp.friends VALUES (2, 'Ulf')");
$stmt = $maxdb->prepare("SELECT id, name FROM temp.friends");
$stmt->execute();
/* get resultset for metadata */
$result = $stmt->result_metadata();
/* retrieve field information from metadata result set */
$field = $result->fetch_field();
printf("Fieldname: %s
", $field->name);
/* close resultset */
$result->close();
/* close connection */
$maxdb->close();
?>
Example #2
Procedural style
<?php
$link = maxdb_connect("localhost", "MONA", "RED", "DEMODB");
maxdb_query($link, "CREATE TABLE temp.friends (id int, name varchar(20))");
maxdb_query($link, "INSERT INTO temp.friends VALUES (1,'Hartmut')");
maxdb_query($link, "INSERT INTO temp.friends VALUES (2, 'Ulf')");
$stmt = maxdb_prepare($link, "SELECT id, name FROM temp.friends");
maxdb_stmt_execute($stmt);
/* get resultset for metadata */
$result = maxdb_stmt_result_metadata($stmt);
/* retrieve field information from metadata result set */
$field = maxdb_fetch_field($result);
printf("Fieldname: %s
", $field->name);
/* close resultset */
maxdb_free_result($result);
/* close connection */
maxdb_close($link);
?>
The above example will output something similar to:
Fieldname: ID
