Top Forums Shell Programming and Scripting Retrieving previous command in a script Post 303002747 by MadeInGermany on Thursday 31st of August 2017 12:36:08 PM

Another technique:
Store the command first, put it into 'ticks'. A tick within ticks is escaped '\''.
When running the command "eval" lets pipes semicolons etc. work.
Code:
#!/bin/sh
CommandA='ps -ef | egrep talling'
eval $CommandA
CommandB='awk '\''/error/ {print $3}'\'' /tmp/test'
eval $CommandB

Or, store the commands in a separate file or have them in a here document,
and read/run them line by line
Code:
#!/bin/sh
while read cmdline
do
  eval $cmdline
done <<'_EOF'
ps -ef | egrep talling
awk '/error/ {print $3}' /tmp/test
_EOF

NAME
script-email - Amanda script to send email notifications DESCRIPTION
script-email is an Amanda script implementing the Script API. It should not be run by users directly. It sends a notification email to the addresses specified in the MAILTO property. PROPERTIES
This section lists the properties that control script-email's functionality. See amanda-scripts(7) for information on the Script API, script configuration. MAILTO List of email addresses that will receive an email on command execution. It is a multi-valued property: property "MAILTO" "amanda@domain.com" "sysadmin@domain.com" "amandauser@domain.com" EXAMPLE
In this example, script-email is scheduled to be run before the DLE, on the server. The unqualified email address amanda will be passed to the email system unchanged. The script is then attached to a dumptype, which can then be specified for any DLEs which require notification. define script-tool pre-email { comment "email me before this DLE is backed up" plugin "script-email" execute-on pre-dle-backup execute-where server property "mailto" "amanda" } define dumptype user-tar-email { user-tar script "pre-email" } SEE ALSO
