Challenging Script question

[Unix or Linux?]

I have a file named File1 with the following data:
Line1
Line2
Line3
Line4
Line5

Im trying to write a script that takes two arguments. The first being a line of text and the second the name of the file above. How do I insert the first argument(line of text) into the first line of the file named above.

For example:

./scriptTest Hello this is a test File1

Would append File1 as such:
Hello this is a test
Line1
Line2
Line3
Line4
Line5

header=$1
filename=$2
(echo $header ;cat $filename) > /tmp/mytmpfile
mv /tmp/mytmpfile $filename


one of the ways how to do it..

forgot to add, if your comment is multiple words containing spaces, make sure to enclose it in quotes.

You're going to have to put quotes around the "Hello this is a test", then your script will look like:

echo $1 > /tmp/file
cat $2 >> /tmp/file
cp /tmp/file $2

Hi:

Using the shell only:

cat ./insertit
#!/usr/bin/sh
echo "${1}" >> "${2}.new"
cat ${2} >> "${2}.new"
mv "${2}.new" "${2}"

# ./insert it ok yourfile

Regards!

Hi is there any other way to do it without having to use quotes. I cant say to the user if you have more than one word then put quotes around it.

So far I have managed the following.

sed -e '1i\' -e "$*" > File1

But this appends the whole line including the second argument.

Can you have the users put the filename first, then-

f=$1
t=/tmp/hold$$
shift
echo $* | cat - $f >$t
mv $t $f

How about the following:

echo hello this is a test file1 | awk '{
for(i=1;i $NF
}'

cheers!

Hi

The line of text has to come first then the file name.

Thank you

Hi Sandman


Im not sure that will work. How does the script know to echo the line of text: Hello this is a test, unless you manually type it in the script.

It could be any line of text.
