This is a classic example of what happens when you run out of system resources like memory. The shell cannot create another process ( fork ) and thus you are restricted to the built-in commands provided by the shell you are using.
You copied the large file in /tmp which is tmpfs and resides on virtual memory. Dumping files in /tmp means consuming virtual memory. In turn, less room for other processes.
In this case, here is what you could do:
All of the commands are shell built-in (work in bourne and korn shells) and shell does not need to fork another process. So, cd lets you in the /tmp directory, echo lets you see the files in that and figure out the name of the file, > brings the size of the file down to zero solving your problem.

Hi All,
My Solaris 8 firewall server is getting full on the / filesystem. I don't know which one should I delete. I think there's no more to delete on the file like logs or temp file.
Does someone knows about deleting a safe file (or folder) on FS like /usr, /opt, /platform, /kernel, /sbin?... (7 Replies)

Hi,
Is there any chance that a file system that mounted on the server becomes read only when the space in that file system becomes full?

Hello,
This is RHEL 5.7. swap is almost full, but I am not sure, what to release and how to release space. This is production server so I would like to try all possible options before reboot.

shell-quote
SHELL-QUOTE(1p) User Contributed Perl Documentation SHELL-QUOTE(1p)NAME
shell-quote - quote arguments for safe use, unmodified in a shell command
SYNOPSIS
shell-quote [switch]... arg...
DESCRIPTION
shell-quote lets you pass arbitrary strings through the shell so that they won't be changed by the shell. This lets you process commands
or files with embedded white space or shell globbing characters safely. Here are a few examples.
EXAMPLES
ssh preserving args
When running a remote command with ssh, ssh doesn't preserve the separate arguments it receives. It just joins them with spaces and
passes them to "$SHELL -c". This doesn't work as intended:
ssh host touch 'hi there' # fails
It creates 2 files, hi and there. Instead, do this:
cmd=`shell-quote touch 'hi there'`
ssh host "$cmd"
This gives you just 1 file, hi there.
process find output
It's not ordinarily possible to process an arbitrary list of files output by find with a shell script. Anything you put in $IFS to
split up the output could legitimately be in a file's name. Here's how you can do it using shell-quote:
eval set -- `find -type f -print0 | xargs -0 shell-quote --`
debug shell scripts
shell-quote is better than echo for debugging shell scripts.
debug() {
[ -z "$debug" ] || shell-quote "debug:" "$@"
}
With echo you can't tell the difference between "debug 'foo bar'" and "debug foo bar", but with shell-quote you can.
save a command for later
shell-quote can be used to build up a shell command to run later. Say you want the user to be able to give you switches for a command
you're going to run. If you don't want the switches to be re-evaluated by the shell (which is usually a good idea, else there are
things the user can't pass through), you can do something like this:
user_switches=
while [ $# != 0 ]
do
case x$1 in
x--pass-through)
[ $# -gt 1 ] || die "need an argument for $1"
user_switches="$user_switches "`shell-quote -- "$2"`
shift;;
# process other switches
esac
shift
done
# later
eval "shell-quote some-command $user_switches my args"
OPTIONS --debug
Turn debugging on.
--help
Show the usage message and die.
--version
Show the version number and exit.
