replace new line with <br /> & escape special characters
 
Hi, I wish to replace a new line with br (html) but it doesn't seem to work
Code:
Code:
message=$(echo ${FORM_message} | tr '\r' '<br \/>' )
what it gives me seems to be ... b...?


I am also having problem escaping hash sign in cut command:
Code:
Code:
list=$(echo "$line" | cut -d'\#;\#' -f1) ;
my intention is to split the line with "#;#"
thanks

Here is a web page with string manipulation commands that are easy to use.

Code:
message=$(echo ${FORM_message//\r/\<br\>})
doesnt work, it doesnt detect for new lines

$'\n' gives a newline character in bash
Code:
FORM_message='line 1
line 2
line 3'

message="${FORM_message//$'\n'/<br>}"
echo "$message"
line 1<br>line 2<br>line 3

# Or the newline can be put in using the return key
message="${FORM_message//
/<br>}"
echo "$message"
line 1<br>line 2<br>line 3

I'm pretty sure 'cut' only accepts a single char for the -d option. Try awk or sed or Perl for more complex replacements.
