When I search for .bashrc files in my system I get:

```
/etc/bash.bashrc
/etc/skel/.bashrc
/root/.bashrc
/usr/share/base-files/dot.bashrc

```

I changed:

```
/etc/bash.bashrc   
/root/.bashrc

```

I added the alias.

```
alias urldecode='python -c "import sys, urllib as ul; \
    print ul.unquote_plus(sys.argv[1])"'

alias urlencode='python -c "import sys, urllib as ul; \
    print ul.quote_plus(sys.argv[1])"'

```

When I run the command:

```
urlencode 'http://example.com space'

```

it works OK from the command line, but when I create an `.sh` file and put the same command there I get:

```
./tf.sh: line 19: urlencode: command not found

```

What is wrong?

Contents of `tf.sh` file:

```
IP=$(curl -d "tool=checurl"-X POST https://site.com/get.py)
url='https://site.com.com/'
path=$(grep -oP '(?<=get.py\?filetype=csv\&data=).*?(?=\")' <<< $IP)
pathfull="get.py?filetype=csv&data=$path"

full=$url$pathfull

#echo $full

urlencode '$full'

```
