sed appending problem
i have a number of java files containing
eg:
Code:
--------------myfile.java--------------
package zip.fun.myfiles;

import java.*
import something..;
import sdfdfdsa;
...
...
--------------------------------------------

Now I need to append / insert a line as follows:

Code:
--------------myfile.java--------------
package zip.fun.myfiles;

import linux.admin.file;
import java.*;
import something..;
import sdfdfdsa;
...
...
--------------------------------------------

i have a shell which contains find command in a forloop
So in the shell inside forloop i tried:
Code:
Try : 1.
sed '/package zip./a \
> import linux.admin.file;' $filename

Try : 2.
var=`cat $filename | nl | grep "package zip." `
tostring="import linux.admin.file; "
sed $var a $tostring -i $filename

Try : 3.
sed -e '/package/G' < $filename | sed 's/^$/import linux.admin.file; /g'

NOT WORKING...!! Smilie

Can u please suggest me the right way..

That works fine for me in RHEL, but AIX is a bit pedantic.

Code:
$ sed '/package zip./ a\
NEW LINE' file1
--------------myfile.java--------------
package zip.fun.myfiles;
NEW LINE

import java.*
import something..;
import sdfdfdsa;
...
...
--------------------------------------------

GNU sed version 4.1.5

No.

I think its some problem in my system.

is there any awk program for appending..

But sed is working in the same script

Code:
I did:
sed -ie "s/${findString}/${replaceString}/g" $filename
in the same script & works fine..

Yes, your sed problem seems a bit strange.

Code:
awk 'NR==3 { print "import linux.admin.file;" } 1' file
