How to avoid Newline character in generated text file?
Hi All,
Just need small help in resolving the special new line character in generated output file.
In one of my shell script I am using following lines to get the spool file (i.e. sfile.txt) and
AAA_XXXX_p111_n222.txt
AAA_YYYY_p111_n222.txt
Here assuming
v_pnum="p111"
v_nid="n222"
HTML Code:
nawk -F"|" -v v1="${v_pnum}" -v v2="${v_nid}" -v v3="${v_opath}" '{
fn=v3 "/AAA_" (length($1)==2?"XXXX":"YYYY") "_" v1 "_" v2 ".txt"
print > fn
}' ${v_opath}/sfile.txt
if [ $? -eq 0 ]
then
sed 's/[ ]*$//' ${v_opath}/AAA_YYYY_${v_pnum}_${v_nid}.txt > ${v_opath}/temp.txt
mv ${v_opath}/temp.txt ${v_opath}/AAA_YYYY_${v_pnum}_${v_nkid}.txt
....
....
....
fi
With this I am getting 2 different files, but when I transfer this file to windows environment and open it in Notepad, I am getting a special new line character (similarly if I place this file in mountpoint folder i.e. having access in UNIX as well as Windows environment, same is the case)
Does anyone have idea like how to avoid this special new line character, or is there a better way of doing the above process.
Example of one of my output files, should look something like this as shown below (if I say Wordwrap no in notepad I get output in well formated)
HTML Code:
AA|222222222|111|222|03/21|2|cccccccccccccccccccccccccccccccccccccccccccccccccc|dddddddd |eeeeeeeeeee |6666666|uuuuuuuuuu | | |2011/03/21| | | |3|6666666|erertertertert|011|222| | | | | | | | | | | | | | | | | | | |

But it is coming with special characters i.e. box like character at the end of each individual line, and the next logical line starting from the end of first line.

escape
escape(1) Mail Avenger 0.8.3 escape(1)
NAME
escape - escape shell special characters in a string
SYNOPSIS
escape string
DESCRIPTION
escape prepends a "" character to all shell special characters in string, making it safe to compose a shell command with the result.
EXAMPLES
The following is a contrived example showing how one can unintentionally end up executing the contents of a string:
$ var='; echo gotcha!'
$ eval echo hi $var
hi
gotcha!
$
Using escape, one can avoid executing the contents of $var:
$ eval echo hi `escape "$var"`
hi ; echo gotcha!
$
A less contrived example is passing arguments to Mail Avenger bodytest commands containing possibly unsafe environment variables. For
example, you might write a hypothetical reject_bcc script to reject mail not explicitly addressed to the recipient:
#!/bin/sh
formail -x to -x cc -x resent-to -x resent-cc
| fgrep "$1" > /dev/null
&& exit 0
echo "<$1>.. address does not accept blind carbon copies"
exit 100
To invoke this script, passing it the recipient address as an argument, you would need to put the following in your Mail Avenger rcpt
script:
bodytest reject_bcc `escape "$RECIPIENT"`
SEE ALSO
avenger(1),
The Mail Avenger home page: <http://www.mailavenger.org/>.
BUGS
escape is designed for the Bourne shell, which is what Mail Avenger scripts use. escape might or might not work with other shells.
