I have a script that creates and then distributes html files via scp on a 60 second cycle. On occasions the scp will hang and not complete with the cycle.
When running the scp command in the back ground it returns the PID. How do I trap $! in the script?
What I want to be able to do is monitor how long the scp runs for, if it is still running 2 minutes after starting then it is hung (can't just ps for the scp command as the scp script is used by multiple applications).

scp
SCP(1) BSD General Commands Manual SCP(1)NAME
scp -- secure copy (remote file copy program)
SYNOPSIS
scp [-pqrvBC46] [-F ssh_config] [-S program] [-P port] [-c cipher] [-i identity_file] [-o ssh_option] [[user@]host1:]file1 [...]
[[user@]host2:]file2
DESCRIPTION
scp copies files between hosts on a network. It uses ssh(1) for data transfer, and uses the same authentication and provides the same secu-
rity as ssh(1). Unlike rcp(1), scp will ask for passwords or passphrases if they are needed for authentication.
Any file name may contain a host and user specification to indicate that the file is to be copied to/from that host. Copies between two
remote hosts are permitted.
The options are as follows:
-c cipher
Selects the cipher to use for encrypting the data transfer. This option is directly passed to ssh(1).
-i identity_file
Selects the file from which the identity (private key) for RSA authentication is read. This option is directly passed to ssh(1).
-p Preserves modification times, access times, and modes from the original file.
-r Recursively copy entire directories.
-v Verbose mode. Causes scp and ssh(1) to print debugging messages about their progress. This is helpful in debugging connection,
authentication, and configuration problems.
-B Selects batch mode (prevents asking for passwords or passphrases).
-q Disables the progress meter.
-C Compression enable. Passes the -C flag to ssh(1) to enable compression.
-F ssh_config
Specifies an alternative per-user configuration file for ssh. This option is directly passed to ssh(1).
-P port
Specifies the port to connect to on the remote host. Note that this option is written with a capital 'P', because -p is already
reserved for preserving the times and modes of the file in rcp(1).
-S program
Name of program to use for the encrypted connection. The program must understand ssh(1) options.
-o ssh_option
Can be used to pass options to ssh in the format used in ssh_config(5). This is useful for specifying options for which there is no
separate scp command-line flag. For example, forcing the use of protocol version 1 is specified using scp -oProtocol=1.
-4 Forces scp to use IPv4 addresses only.
-6 Forces scp to use IPv6 addresses only.
DIAGNOSTICS
scp exits with 0 on success or >0 if an error occurred.
