Shell Programming and Scripting

Code:

sed '/patternstring/ a\ new line string' file1

The above code is not working even with the i option....
it shows sed grambled if '\' after new line string is not being used....after using no changes it is displaying..Pls help

Use code tags for code and data sample.

Try

Code:

sed 's/patternstring/\n new line string/' file

it is still not working

Try placing what follows the backslash on the next line.

That is absolutely useless feedback. Tell us which sed implementation and operating system you're using. Show us the command you ran. Show us the data that's the input for the command. Show us the incorrect output that is being generated. And, finally, show us the correct output that you desire.


A lot of sed implementations (and the POSIX standard) do not support the \n newline escape sequence in replacement text. The portable approach is to use a backslash followed by a literal newline.

The file which is used is

Code:

/abc/apps/cobbbbbb/apps/abadv/binder/axyz.bnd
/abc/apps/cobbbbbb/apps/abbrio/binder/na6115.bnd
/abc/apps/cobbbbbb/apps/abbrio/binder/kc22.bnd
/abc/apps/cobbbbbb/apps/abbrio/binder/tr4823.bnd
/abc/apps/cobbbbbb/apps/abcmp/binder/cpc0105.bnd

The commads which I ran through are:

Code:

sed '/axyz.bnd/ a\grant permissions given  ' file1

and

Code:

sed '/axyz.bnd/  i\grant permissions given  ' file1

..
If above commands are given it is showing an error so i added a '\'

Code:

sed '/axyz.bnd/  i\grant permissions given \ ' file1

..This time no error but no output..Pls help
