please solve ${tpPath##a}

nagendrar · 05-07-2010, 06:54 AM

I have following code in script

Code:

tpPath="adae"
tempPath=${tpPath##a}
echo $tempPath

If first character is "a" then It replaces with empty string.
It works fine in linux but on solaris i am getting "bad substitution" error

Please help me to fix this

ThanQ,
Nagendra

Hi,

Like in your other thread, this probably isn't supported in the shell you are using.

This should do what you want (strip the first a if present):
echo $tpPath | sed 's/^a//'

Hope this helps.

Please don't start a new thread when the issue is so similar to the other one.

The root cause isn't that much Solaris vs Gnu/Linux, just different shells. The simpler for you might be to switch to a shell that support the used syntax, likely bash.
