Adding to the end of the path in .profile
Hi there,

I have the following in my path:
Code:
export PATH=/usr/bin:/usr/sbin

But I want to change it programmatically(for the purpose of JBoss automatic(ansible) installs) to:
Code:
export PATH=/usr/bin:/usr/sbin:/usr/jdk/jdk1.8.0_60

and after that I need to insert the JAVA_HOME programmatically, but not now...

So, after trawling the www for answers... I thought that this one is the least confusing (not allowed to insert the http Smilie

unix.com >> shell-programming-and-scripting >> 32168-replace-directory-path-another-file.html


Code:
sed 's_export PATH=/usr/bin:/usr/sbin_export PATH=/usr/bin:/usr/sbin:/usr/jdk/jdk1.8.0_60_g' .profile > xx

But I get the following result:
Code:
sed: command garbled: s_export PATH=/usr/bin:/usr/sbin_export PATH=/usr/bin:/usr/sbin:/usr/jdk/jdk1.8.0_60_g

Is there anyone out there that can help me Smilie

You need to use a different RE delimiter, because _ also occurs in the replacement string. Instead of _ try |
Code:
sed 's|export PATH=/usr/bin:/usr/sbin|export PATH=/usr/bin:/usr/sbin:/usr/jdk/jdk1.8.0_60|g' .profile

or
Code:
sed 's|export PATH=/usr/bin:/usr/sbin|&:/usr/jdk/jdk1.8.0_60|g' .profile

or perhaps even
Code:
sed 's|export PATH=.*|&:/usr/jdk/jdk1.8.0_60|g' .profile

Too late Smilie

Hi,
Your problem is your character's choice '_' in s command, because jdk1.8.0_60 containt '_'.

Regards.

I think a typo sneaked into the replacements... There isn't any need for a global substitution here. I think you meant:
Code:
sed 's|export PATH=/usr/bin:/usr/sbin|export PATH=/usr/bin:/usr/sbin:/usr/jdk/jdk1.8.0_60_g|' .profile

or
Code:
sed 's|export PATH=/usr/bin:/usr/sbin|&:/usr/jdk/jdk1.8.0_60_g|' .profile

or
Code:
sed 's|export PATH=.*|&:/usr/jdk/jdk1.8.0_60_g|' .profile

Ah yes, so it did, absolutely correct Smilie !

-- edit --

Hold on actually, I think it should be:

Code:
sed 's|export PATH=/usr/bin:/usr/sbin|export PATH=/usr/bin:/usr/sbin:/usr/jdk/jdk1.8.0_60|' .profile

or
Code:
sed 's|export PATH=/usr/bin:/usr/sbin|&:/usr/jdk/jdk1.8.0_60|' .profile

or perhaps even
Code:
sed 's|export PATH=.*|&:/usr/jdk/jdk1.8.0_60|' .profile

Ah, yes. Scrutinizer just copied the unneeded g flag from hvdalsen's initial code.

Sorry for the confusion.

You probably want to save your changes, and mayhap back to the original file? Make it
Code:
sed '...' .profile  >TMP && mv TMP  .profile

, then.
