Thanks the eval worked... but it doesn't full work with the varible... tried with echo didn't seem to work. Just outputed it to the screen.


t1="sed -e 's/http:/<li><a href=\"http:/'"
t2="sed -e 's/http:.*/&\">&<\/a>Web Link<br>/'"
t3="sed -e 's/.*[0-9]. mailto:/<li><a href=\"mailto:/'"
t4="sed -e 's/mailto:.*/&\">&<\/a>Email Link<br>/'"
#lastcmd="eval $t1| eval $t2| eval $t3| eval $t4 | sort |uniq"


lynx -dump "$1" | \
sed -e '1,/^References$/d' \
-e 's/.*[0-9]. //' | \
eval $t1| eval $t2| eval $t3| eval $t4 | sort |uniq


That will work however I would like to replace the
"eval $t1| eval $t2| eval $t3| eval $t4 | sort |uniq" with $last command..

THe #ed line above will not work when called like this...
lynx -dump "$1" | \
sed -e '1,/^References$/d' \
-e 's/.*[0-9]. //' | \
eval $lastcmd

or using $lastcmd with out the eval....


Any suggestions of how to put those all inside lastcmd ?

Thanks.

uniq

UNIQ(1) 							   User Commands							   UNIQ(1)

NAME

       uniq - report or omit repeated lines

SYNOPSIS

       uniq [OPTION]... [INPUT [OUTPUT]]

DESCRIPTION

       Discard all but one of successive identical lines from INPUT (or standard input), writing to OUTPUT (or standard output).

       Mandatory arguments to long options are mandatory for short options too.

       -c, --count
	      prefix lines by the number of occurrences

       -d, --repeated
	      only print duplicate lines

       -D, --all-repeated[=delimit-method]
	      print all duplicate lines delimit-method={none(default),prepend,separate} Delimiting is done with blank lines.

       -f, --skip-fields=N
	      avoid comparing the first N fields

       -i, --ignore-case
	      ignore differences in case when comparing

       -s, --skip-chars=N
	      avoid comparing the first N characters

       -u, --unique
	      only print unique lines

       -z, --zero-terminated
	      end lines with 0 byte, not newline

       -w, --check-chars=N
	      compare no more than N characters in lines

       --help display this help and exit

       --version
	      output version information and exit

       A field is a run of blanks (usually spaces and/or TABs), then non-blank characters.  Fields are skipped before chars.

       Note:  'uniq'  does  not  detect  repeated  lines unless they are adjacent.  You may want to sort the input first, or use `sort -u' without
       `uniq'.
