In the kornshell you can get the length of a string with
$ x=abc
$ print ${#x}

If the current locale is a multibyte locale, like de_AT.UTF-8, you get the length of the string in bytes, not characters:
$ x=für
$ print ${#x}

SVN-BISECT(1) General Commands Manual SVN-BISECT(1)NAME
svn-bisect - Bisect Subversion revisions to find a regression
SYNOPSIS
svn-bisect start [good_rev [bad_rev]]
svn-bisect {good|bad} [rev]
svn-bisect run command
svn-bisect reset
svn-bisect status
DESCRIPTION
svn-bisect helps to automate finding a bug or behavior change in a Subversion working copy. Given an initial "good" revision, with the
desired or original behavior, and a newer "bad" revision, with the undesired or modified behavior, svn-bisect will do a binary search
through the revision range to find which revision caused the change.
svn-bisect must be initialized in a working copy, with svn-bisect start. It also needs to be given at least one good revision (the base-
line) and one bad revision (known modified behavior) revision.
Sub-commands:
start Initializes or reinitializes svn-bisect; optionally takes good and bad revision parameters.
good rev
bad rev
Tells svn-bisect that a revision is good or bad, defining or narrowing the search space. If not specified, revision defaults to the
current revision in the working copy. svn-bisect will then update to a revision halfway between the new good and bad boundaries.
If this update crosses a point where a branch was created, it switches in or out of the branch.
reset Resets the working copy to the revision and branch where svn-bisect start was run. In the simple case this is equivalent to rm -r
.svn-bisect; svn update, but not if it has crossed branches, and not if you did not start at the HEAD revision. In any case,
svn-bisect never keeps track of mixed-revision working copies, so do not use svn-bisect in a working copy that will need to be
restored to mixed revisions.
status Prints a brief status message.
run command
Runs the bisection in a loop. You must have already defined initial good and bad boundary conditions. Each iteration through the
loop runs command as a shell command (a single argument, quoted if necessary) on the chosen revision, then marks the revision as
good or bad, based on the exit status of command.
EXAMPLES
Assume you are trying to find which revision between 1250 and 1400 caused the make check command to fail.
svn-bisect start 1250 1400
svn-bisect run 'make check'
svn-bisect reset
ENVIRONMENT
SVN The Subversion command-line program to call (default svn).
FILES
.svn-bisect
The directory containing state information, removed after a successful bisection.
