Hi,

Can any one help me out, My exact requirement is

For example
I need to read the file called abc.cpp and write it into new file called xyz.cpp while I write it should remove all comment line from abc.cpp.

Exp :

abc.cpp

include <stdio.h>
/* This is program is for
Identify Author access level */
void main()
{
int ja_Key; /* key for ALOT */
public rePaid()
{
cout<<”Test Script”;
} /* comment may come here */

}

In the above program

/* */ are comment line

My xyz.cpp program should be like that.


include <stdio.h>
void main()
{
int ja_Key;
public rePaid()
{
cout<<”Test Script”;
}
}

Thanks & Regards

K.Swaminathan


I have tryed with this command

sed

sed -e ':^/*:,:*e$:d' abc.cpp > xyz.cpp
error is :
sed: 0602-417 The label :^/*:,:*e$:d is greater than eight characters.

awk

$ cat RK
stuff I do not want
[string1]
I just want
these two lines
[string2]
more stuff I do not want
$ awk '/^\[string1\]/,/^\[string2\]/' rk
[string1]
I just want
these two lines
[string2]

I want to delete the content How to do that in awk

but I want to sort out /* .. */ string

HI swamijc,
try this :

# change to the path where your file exist
#cd
#cd bin
cat abc.ccp | awk ' BEGIN { FS="\n"; Comment="OFF" }
{
i=0
row=""
lang=length($1)
while ( i <= lang )
{
i=i+1
if ( substr($1,i,1) == "/" )
{
if ( substr($1,i+1,1) == "*" )
{
Comment="ON"
i=i+2
}
}
if ( substr($1,i,1) == "*" )
{
if ( substr($1,i+1,1) == "/" )
{
Comment="OFF"
i=i+2
}
}
if ( Comment=="OFF" )
{
row=row""substr($1,i,1)
}
}
if ( row != "" )
{
print row > "xyz.ccp"
}
}'
