In bash, you can use "ulimit -n" to raise the maximum number of
open files:
$ ulimit -a
core file size (blocks, -c) 0
data seg size (kbytes, -d) 6144
file size (blocks, -f) unlimited
max locked memory (kbytes, -l) unlimited
max memory size (kbytes, -m) unlimited
open files (-n) 256
pipe size (512 bytes, -p) 1
stack size (kbytes, -s) 512
cpu time (seconds, -t) unlimited
max user processes (-u) 100
virtual memory (kbytes, -v) 6656
$ ulimit -n 512
$ echo $?
0
$ ulimit -a
...
open files (-n) 512
...
The tcsh equivalent should be "limit" but it seems that the maximum
number of open files can't be modified with this command.
And in the general case, you can use the module FileCache, present
in the core distribution of Perl:
NAME
FileCache - keep more files open than the system permits
SYNOPSIS
cacheout $path;
print $path @data;
