How do I extract a substring using tcl
Posted on 2006-07-10
Hello, I need to extract a substring from another string using tcl.
I have tried using regexp without success.
Here is an example of what I need to do:
string1 = "22/OBGJ/123456_5.66:22/OB
result
"22/OBGJ/123456_5.66"
I need to extract the entire substring upto but NOT including the ":" character.
Is there a simple solution for this?
Much thanks!

I should clarify that this is for tcl, not shell scripting.
I was not able to find a Tcl related channel, I apologize if this is not the best place to pose the question.

set x "22/OBGJ/123456_5.66:22/OB
puts "[string range $x 0 [expr [string first ":" $x] - 1]]" ;# [string first ":" $x] gives you the index of the first ":" and use [expr theposition - 1] to get the index - 1 position, then string range just extract out the substring
