I have encountered a very weird behavior of a global variable in Korn Shell in AIX:
A function f1 in my script pipes the output of the function f2 to a program.
A variable defined as global using typeset gets its value in f2.
That value is not seen in f1. If I remove the pipe ksh recognizes the... (2 Replies)

Hi,
gtkdialog gui seperate buttons use seperate functions in their GUI. A variable (newFolderName) is being set in one function (funcA) and it needs to be called in another function (funcB). I thought using global variable (like in python) concept should work however it does not.

GIT-CHERRY(1) Git Manual GIT-CHERRY(1) NAME
git-cherry - Find commits yet to be applied to upstream SYNOPSIS
git cherry [-v] [<upstream> [<head> [<limit>]]] DESCRIPTION
Determine whether there are commits in <head>..<upstream> that are equivalent to those in the range <limit>..<head>. The equivalence test is based on the diff, after removing whitespace and line numbers. git-cherry therefore detects when commits have been "copied" by means of git-cherry-pick(1), git-am(1) or git-rebase(1). Outputs the SHA1 of every commit in <limit>..<head>, prefixed with - for commits that have an equivalent in <upstream>, and + for commits that do not. OPTIONS
-v Show the commit subjects next to the SHA1s. <upstream> Upstream branch to search for equivalent commits. Defaults to the upstream branch of HEAD. <head> Working branch; defaults to HEAD. <limit> Do not report commits up to (and including) limit. EXAMPLES
Patch workflows git-cherry is frequently used in patch-based workflows (see gitworkflows(7)) to determine if a series of patches has been applied by the upstream maintainer. In such a workflow you might create and send a topic branch like this: $ git checkout -b topic origin/master # work and create some commits $ git format-patch origin/master $ git send-email ... 00* Later, you can see whether your changes have been applied by saying (still on topic): $ git fetch # update your notion of origin/master $ git cherry -v Concrete example In a situation where topic consisted of three commits, and the maintainer applied two of them, the situation might look like: $ git log --graph --oneline --decorate --boundary origin/master...topic * 7654321 (origin/master) upstream tip commit [... snip some other commits ...] * cccc111 cherry-pick of C * aaaa111 cherry-pick of A [... snip a lot more that has happened ...] | * cccc000 (topic) commit C | * bbbb000 commit B | * aaaa000 commit A |/ o 1234567 branch point In such cases, git-cherry shows a concise summary of what has yet to be applied: $ git cherry origin/master topic - cccc000... commit C + bbbb000... commit B - aaaa000... commit A Here, we see that the commits A and C (marked with -) can be dropped from your topic branch when you rebase it on top of origin/master, while the commit B (marked with +) still needs to be kept so that it will be sent to be applied to origin/master. Using a limit The optional <limit> is useful in cases where your topic is based on other work that is not in upstream. Expanding on the previous example, this might look like: $ git log --graph --oneline --decorate --boundary origin/master...topic * 7654321 (origin/master) upstream tip commit [... snip some other commits ...] * cccc111 cherry-pick of C * aaaa111 cherry-pick of A [... snip a lot more that has happened ...] | * cccc000 (topic) commit C | * bbbb000 commit B | * aaaa000 commit A | * 0000fff (base) unpublished stuff F [... snip ...] | * 0000aaa unpublished stuff A |/ o 1234567 merge-base between upstream and topic By specifying base as the limit, you can avoid listing commits between base and topic: $ git cherry origin/master topic base - cccc000... commit C + bbbb000... commit B - aaaa000... commit A SEE ALSO
