SED Substitution
Hi ,
I am stuck up in the below scenario:-
I need to read a file name (eg A.txt) name frm another file (eg B.txt) and then I need to search for a particular expression in A.txt and substitute it with another expression.
How can I use SED inside SHELL Scripting and command prompt as well to execute the above problem.
The below is the script which I was trying to execute but I am not getting the desired O/P
++++++++++++++++++++++++++++++++++++++++++++++++
#!/bin/sh
FILE="$1"
echo ############################
echo $FILE
echo ############################
exec 3<&0
exec 0<$FILE
while read line
do
echo ############################
echo $line
echo ############################
FILE1="$line"
echo ############################
echo $FILE1
echo ############################
sed 's/feature\/frame\/work/vobs\/syscomp02\/comm\/work/' $FILE1
done
exec 0<&3
+++++++++++++++++++++++++++++++++++++++++++++++++++++
Where $1 is the input file which has the name of files to be edited.
Could someone please help?
Thanks in Advance,
SD.

For example: sed 's/(old variable)/(new variable)/ details.dat
Am I suppose to put $old variable or whatever? Because I tried many times, it didnt work by putting $old variable. Am I suppose to enclose it with "" or ''?

gensprep
gensprep(8) ICU 50.1.2 Manual gensprep(8)
NAME
gensprep - compile StringPrep data from files filtered by filterRFC3454.pl
SYNOPSIS
gensprep [ -h, -?, --help ] [ -v, --verbose ] [ -c, --copyright ] [ -s, --sourcedir source ] [ -d, --destdir destination ]
DESCRIPTION
gensprep reads filtered RFC 3454 files and compiles their information into a binary form. The resulting file, <name>.icu, can then be read
directly by ICU, or used by pkgdata(8) for incorporation into a larger archive or library.
The files read by gensprep are described in the FILES section.
OPTIONS
-h, -?, --help
Print help about usage and exit.
-v, --verbose
Display extra informative messages during execution.
-c, --copyright
Include a copyright notice into the binary data.
-s, --sourcedir source
Set the source directory to source. The default source directory is specified by the environment variable ICU_DATA.
-d, --destdir destination
Set the destination directory to destination. The default destination directory is specified by the environment variable ICU_DATA.
ENVIRONMENT
ICU_DATA Specifies the directory containing ICU data. Defaults to /usr/share/icu/50.1.2/. Some tools in ICU depend on the presence of the
trailing slash. It is thus important to make sure that it is present if ICU_DATA is set.
FILES
The following files are read by gensprep and are looked for in the source /misc for rfc3454_*.txt files and in source /unidata for Normal-
izationCorrections.txt.
rfc3453_A_1.txt Contains the list of unassigned codepoints in Unicode version 3.2.0....
rfc3454_B_1.txt Contains the list of code points that are commonly mapped to nothing....
rfc3454_B_2.txt Contains the list of mappings for casefolding of code points when Normalization form NFKC is specified....
rfc3454_C_X.txt Contains the list of code points that are prohibited for IDNA.
NormalizationCorrections.txt
Contains the list of code points whose normalization has changed since Unicode Version 3.2.0.
