This way maybe?
Code:
#!/bin/sh

#Default values
TEXT="Data_0"
Lines=45

if [ "$1" ]; then
	[ "$1" -eq 0 ] >/dev/null 2>&1; x="$?"
	if [ "$x" -lt 2 ]; then 	
		echo "Arg is an integer, to be set to Lines"
		Lines="$1"
	else
		echo "Arg is not an integer, so, it's probably some text"
		TEXT="$1"
	fi
fi

Hi tukuyomi,
Thanks for the reply !
As I understood it would work. But I need to provide both argument together. But yeah ECHO would help in recalling as what argument should be text and what should be integer?

Am I correct?

I think you are very confused or i am confused Smilie

do you want to run one script multiple times and pass argument.

if you want to get return from the script as what type of argument is passed then just verify the string with numeric or characters..

Code:
./script.sh text
# here $1=text you can perform the operation here..

./script.sh 10
#here also $1=10

If i am guessing right you might talking about after running script 2 you want $2 as 10 right..?


That's not possible as per my knowledge.

hope it helps you..

and for checking string or integer check this...

Code:
$ [[ `echo "adsds" | sed 's/^[-+0-9][0-9]*//' | wc -c` -eq 1 ]] && echo "itz number" || echo "itz not number"
itz not number

$ [[ `echo "1022" | sed 's/^[-+0-9][0-9]*//' | wc -c` -eq 1 ]] && echo "itz number" || echo "itz not number"
itz number

$ [[ `echo "10df22" | sed 's/^[-+0-9][0-9]*//' | wc -c` -eq 1 ]] && echo "itz number" || echo "itz not number"
itz not number

You want your script to take
Code:
./script.sh text
./script.sh integer
./script.sh text integer

all three at the same time?
Or Am I confused as well? :s

Try this :
Code:
#!/bin/sh

#Define a function
intortext() {
	[ "$1" ] || return 0
	[ "$1" -eq 0 ] >/dev/null 2>&1; x="$?"
	if [ "$x" -lt 2 ]; then 	
		echo "Arg is an integer, to be set to Lines"
		Lines="$1"
	else
		echo "Arg is not an integer, so, it's probably some text"
		TEXT="$1"
	fi
}

#Default values
TEXT="Data_0"
Lines=45

#main()
intortext "$1"
intortext "$2"

If your question is how to use it with only parameter 2, use this:
Code:
 ./script.sh "" integer

And I would prefer if [ -z "$1" ]... instead of if [ ! "$1" ]...
