Inserting text in a specific file in a specific point

Inserting text in a specific file in a specific point

[MARG]

Hi,

My .bash_profile is:
----------------------
# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
	. ~/.bashrc
fi

# User specific environment and startup programs

PATH=$PATH:$HOME/bin

export PATH
unset USERNAME
----------------------------

What i'd like to do is from the command prompt or a bash script, insert
text after the line "PATH=$PATH:$HOME/bin".

I've searched the web and tried a few tricks, but one worked :(

Could you help me please ?

Wam Regards,
MARG

sed is the tool you need.

Try something like:

sed -e '10a\some text\' .bash_profile

Hi Darren,

Thank you for your answer.

I tried that already and it works.

Problem is,  it is assuming that the PATH line is line 10 and in other
systems it may not be.

Any ideas ?

Warm Regards,
MARG
PS: Thank you Scott for the cool link.

Ok, so you will have to use sed to find the PATH line using a regex, then 
print your line right after...

sed -e '/PATH=\$PATH/a some text' .bash_profile
