change path permanently

[Red Squirrel]

I have a folder in /data/scripts that I want to set as my path.

I tried export path=$path:/data/scripts

The first time it worked, so figured perfect, so I added it to my rc.local file... but suddently the command itself stopped working. I rebooted the server, and it did not take affect, so I typed it manually, it did not take affect.

So is there a different way of doing it that's consistant?

use pathmunge in /etc/profile

here's an example of setting java's directory and intel's c++ compiler into the path using pathmunge.

Code: Select all

# /etc/profile

# System wide environment and startup programs, for login setup
# Functions and aliases go in /etc/bashrc

pathmunge () {
        if ! echo $PATH | /bin/egrep -q "(^|:)$1($|:)"; then
    if [ "$2" = "after" ]; then
       PATH=$PATH:$1
    else
       PATH=$1:$PATH
    fi
        fi
}

# Path manipulation
if [ `id -u` = 0 ]; then
        pathmunge /sbin
        pathmunge /usr/sbin
        pathmunge /usr/local/sbin
fi

pathmunge /usr/X11R6/bin after

JAVA_HOME=/usr/java/j2sdk1.4.2_02
pathmunge $JAVA_HOME/bin after
export JAVA_HOME

ICC_HOME=/usr/local/intel/compiler70/ia32
pathmunge $ICC_HOME/bin after
export ICC_HOME

KOMODO_HOME=/usr/local/Komodo-2.5
pathmunge $KOMODO_HOME after
export KOMODO_HOME

unset pathmunge

# No core files by default
ulimit -S -c 0 > /dev/null 2>&1

USER="`id -un`"
LOGNAME=$USER
MAIL="/var/spool/mail/$USER"

HOSTNAME=`/bin/hostname`
HISTSIZE=1000

if [ -z "$INPUTRC" -a ! -f "$HOME/.inputrc" ]; then
    INPUTRC=/etc/inputrc
fi

export PATH USER LOGNAME MAIL HOSTNAME HISTSIZE INPUTRC

for i in /etc/profile.d/*.sh; do
    if [ -r "$i" ]; then
            . $i
    fi
done

unset i

holy crap did not know it would be that complicated. mind explaining that line by line or pointing me to a resource, I don't even know where I would put the actual path in that code...

all you really need is the pathmunge line. if you want to create an environment variable use this block of code.

Code: Select all

JAVA_HOME=/usr/java/j2sdk1.4.2_02
pathmunge $JAVA_HOME/bin after
export JAVA_HOME

the first line creates an environment variable called JAVA_HOME and sets its value to /usr/java/j2sdk1.4.2_02

the second line, puts the path at the end of your existing list of paths.

the third line exports the variable for use.

i think you can just get away with the second line.
ex. --> pathmunge /data/scripts after

put that line after root's path is set (the if/fi block starting with the comment "Path Manipulation") but before the "unset pathmunge" line.
