I tried to do grep '/foldername:' $PATH

and also '/foldername:' PATH

both do not work.

How can I do it?

is there another function

Peace,

echo $PATH | grep <search term>

If the directory named "search term" is in your path, you'll get back a string, otherwise, null.

I get:

bash: syntax error near unexpected token `newline'

When I enter

echo $PATH | grep </usr>

Peace,

LOL....... I knew i should've took the <> from the search string..

thanks alot brother

Peace,

I actually tried this:



if ( $PATH | grep $1 ) 2> /dev/null
then
echo "Directory Already Exists in PATH"
else
PATH=/$1:$PATH
echo "Directory Has Been added to PATH"
fi




seems to be adding the thing all over...

Peace,

Ok worked around it... added echo..

the problem is it still echos the results even when I do > dev.null

Peace,

2> is only redirecting stderr.

Um... just a question about this:

PATH=/$1:$PATH

What's the slash doing there?

Sorry, stepped away for a few hours. Shame on me! :)

A couple of things to get it working.

As inimino said, you need a different redirect. This will work:


if ( echo $PATH | grep $1 ) >& /dev/null


Also as inimino said, what's the leading slash for?

You might want to try this (use export):


export PATH=$1:$PATH

Woked fine.. thanks alot guys..

this is the code I made:


#!/bin/ksh

#Aziz Hussain
#Install :: Install File
#1307
#This script will accept exactly two arguments, first is a file location the second is a directory. Copy the file to the directory and then add that directory to the PATH variable

if [[ $# < 2 ]]
# Check if exactly two arguments has been passed
then
echo "You Must Enter Two Arguments"
else
if [[ -d $1 ]] 2> /dev/null
#Check if a directory is valid
then
if [[ -a $2 ]] 2> /dev/null
#If so then check if the file exists
then
cp $2 $1/$2
if ( echo $PATH | grep $1 ) > /dev/null
then
echo "Directory Already Exists in PATH"
else
PATH=/$1:$PATH
echo "Directory Has Been added to PATH"
fi
else
echo "Invalid File Entered"
fi
else
echo "Invalid Directory Specified"
fi
fi
#End of Script



As you might see the trailing slash it to add it as a folder..

tee:

will be /tee:

Peace,

Looks mostly ok.

About the leading slash, you're trying to make an absolute directory out of whatever is handed to your script.

But the "/" doesn't quite accomplish that.

For example, what if I am in my home directory and I enter "bin" as the first argument.
Then it will fail because /bin is already in the PATH.

It's possible to "cd" to the $1 which will also ensure that the user has permission to do so.
Then you can simply use 'pwd' to find what you add to $PATH.

Only absolute paths should be added to $PATH.

HTH,
