Append the end of each line in a file with a given string
Hi friends,

I have a file containing many lines as follows.

Code:
M:\mmarimut_v6.4.0_pit_01\java\build.xml@@\main\v6.4.0_pit_a
M:\mmarimut_v6.4.0_pit_01\ADBasicView.java@@\main\v6.4.0_pit_a

I would like to append the string "\0" at the end of each line in the file. The output should look like:

Code:
M:\mmarimut_v6.4.0_pit_01\java\build.xml@@\main\v6.4.0_pit_a\0
M:\mmarimut_v6.4.0_pit_01\ADBasicView.java@@\main\v6.4.0_pit_a\0

I tried this command but in vain. Please help me. Thanks in advance.

Code:
awk '{print $0,"\0"}' C:\LOC\v6.4.0_test.txt > C:\LOC\v6.4.0_awktest.txt

Escape the backslash:

Code:
awk '{print $0 "\\0"}' file > newfile

or with sed:

Code:
sed 's/.*/&\\0/' file > newfile

use below:-
in solaris use nawk or /usr/xpg4/bin/awk;
in other systems use gawk.


Code:
nawk '{$0=$0"\\O" }1' infile.txt > outfile.txt

Thanks Ahmad.diab for a quick reply. I had tried to escape the back slash but it didnt work for me. I am working on windows and sed doesnt work for me, so the only option is to use awk. Any alternative just let me know. Thanks again.

Thanks,

if you are using cygwin do the below:-

Code:
gawk '{$0=$0"\\O" }1' infile.txt > outfile.txt

note:- $0 in words is $zero

Append the end of each line in a file with a given string
Hi ahmad.diab, i tried gawk '{$0=$0\\0 }1' infile.txt > outfile.txt but the result is not as expected. It appends a special character at the end. I am unable to copy the special character. And more over the string to be attached is a (\0 ie \zero). Any suggestions. Thanks.

be careful you have to put the quotation marks ("") around your string or the system will translate the \\0 to NULL string.


Code:
gawk '{$0=$0"\\0" }1' infile
