First, you want to chop off 3 dirs; cut, sed, awk or even just shell pattern chopping (${name#pattern}, ${name%%pattern} ) can do this.
Second, you want to add a line break before 'to200', and again, sed, awk or shell pattern chopping. See man bash look for %%:
Quote:
${parameter#word}
${parameter##word}
The word is expanded to produce a pattern just as in pathname expansion. If the
pattern matches the beginning of the value of parameter, then the result of the
expansion is the expanded value of parameter with the shortest matching pattern
(the ``#'' case) or the longest matching pattern (the ``##'' case) deleted. If
parameter is @ or *, the pattern removal operation is applied to each positional
parameter in turn, and the expansion is the resultant list. If parameter is an
array variable subscripted with @ or *, the pattern removal operation is applied to
each member of the array in turn, and the expansion is the resultant list.
${parameter%word}
${parameter%%word}
The word is expanded to produce a pattern just as in pathname expansion. If the
pattern matches a trailing portion of the expanded value of parameter, then the
result of the expansion is the expanded value of parameter with the shortest match-
ing pattern (the ``%'' case) or the longest matching pattern (the ``%%'' case)
deleted. If parameter is @ or *, the pattern removal operation is applied to each
positional parameter in turn, and the expansion is the resultant list. If parame-
ter is an array variable subscripted with @ or *, the pattern removal operation is
applied to each member of the array in turn, and the expansion is the resultant
list.
The sed/awk '.*' is always aggressive, but the pattern chop allows you to select aggressive or minimal wild card. I faintly recall MULTICS qedx or Waterloo FRED allowed you to select, too.
My mnemonic for remembering them is "#" is pound like 'pound on the nose", and '%' is like for a broker or artistliving off royalties, 'take my percentage at the end'.

tcl_stringcasematch
Tcl_StringMatch(3) Tcl Library Procedures Tcl_StringMatch(3)
__________________________________________________________________________________________________________________________________________________
NAME
Tcl_StringMatch, Tcl_StringCaseMatch - test whether a string matches a pattern
SYNOPSIS
#include <tcl.h>
int
Tcl_StringMatch(string, pattern)
int
Tcl_StringCaseMatch(string, pattern, nocase)
ARGUMENTS
char *string (in) String to test.
char *pattern (in) Pattern to match against string. May contain special characters from the set *?[].
int nocase (in) Specifies whether the match should be done case-sensitive (0) or case-insensitive (1).
_________________________________________________________________
DESCRIPTION
This utility procedure determines whether a string matches a given pattern. If it does, then Tcl_StringMatch returns 1. Otherwise
Tcl_StringMatch returns 0. The algorithm used for matching is the same algorithm used in the ``string match'' Tcl command and is similar
to the algorithm used by the C-shell for file name matching; see the Tcl manual entry for details. |
In Tcl_StringCaseMatch, the algorithm is the same, but you have the option to make the matching case-insensitive. If you choose this (by |
passing nocase as 1), then the string and pattern are essentially matched in the lower case.
KEYWORDS
match, pattern, string
Tcl 8.1 Tcl_StringMatch(3)
