Sort files by number at end in bash/perl -

-

i'm trying sort huge list of files following format:

file-55_357-0.csv file-55_357-1.csv file-55_357-2.csv  file-55_357-3.csv  ...

is there simple way in bash or perl? in other words, there way write perl script such goes through of them in numerical order? instance, when create my @files, can make sure script goes through them in sorting -- how create my @sorted array? ask because want append these files vertically, , need in sorted order. much!

you can use sort command, neither part of bash nor part of perl.

with input data in input.txt:

file-55_357-123.csv file-55_357-0.csv file-55_357-21.csv  file-55_357-3.csv

from shell, (any shell, not bash) can following:

$ sort -t- -nk3 input.txt file-55_357-0.csv file-55_357-3.csv file-55_357-21.csv file-55_357-123.csv

the -t option specifies delimiter, -n says compare numeric values (so 21 comes after 3 rather before) , -k 3 says sort on third field (per delimiter).

mysql - FireDac error 314 - but DLLs are in program directory -

i getting when trying access mysql database : [firedac][phys][mysql]-314. cannot load vendor library [libmysql.dll or libmysqlld.dll] this did not happen (unchanged) code, however, have upgraded windows 10 , had reinstall delphi xe8, system configuration matter. in order try solve problem, copied both of files c:\windows\sysytem32. when did not seem work, copied them \win32\debug, generated .exe resides. i imagine doing rather stupid, can't see what. the proper solution place driver file (eg., libmysql.dll ) in application's folder, or place installation location in fddrivers.ini file: [mysql] vendor=<folder>\libmysql.dll (recent versions of documentation seem use vendorlib instead of vendor in ini file.) see rad studio documentation topics configuring drivers (firedac) , connect mysql server (firedac) more information.
