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 ?

PAPS(1) General Commands Manual PAPS(1)
NAME
paps - UTF-8 to PostScript converter using Pango
SYNOPSIS
paps [options] files...
DESCRIPTION
paps reads a UTF-8 encoded file and generates a PostScript language rendering of the file. The rendering is done by creating outline curves
through the pango ft2 backend.
OPTIONS
These programs follow the usual GNU command line syntax, with long options starting with two dashes (`-'). A summary of options is
included below.
--landscape
Landscape output. Default is portrait.
--columns=cl
Number of columns output. Default is 1.
--font=desc
Set the font description. Default is Monospace 12.
--rtl Do rtl layout.
--paper ps
Choose paper size. Known paper sizes are legal, letter, a4. Default is A4.
--bottom-margin=bm
Set bottom margin in postscript points (1/72 inch). Default is 36.
--top-margin=tm
Set top margin. Default is 36.
--left-margin=lm
Set left margin. Default is 36.
--right-margin=rm
Set right margin. Default is 36.
--help Show summary of options.
--header
Draw page header for each page.
--markup
Interpret the text as pango markup.
--encoding=ENCODING
Assume the documentation encoding is ENCODING.
--lpi Set the lines per inch. This determines the line spacing.
--cpi Set the characters per inch. This is an alternative method of specifying the font size.
--stretch-chars
Indicates that characters should be stretched in the y-direction to fill up their vertical space. This is similar to the texttops
behaviour.
