+# Purpose:
+# . Run same UniBoard command on remote dish LCUs in parallel
+# Usage:
+# . python run_command_on_lcus.py --tel <telescopes 2,3,4,..,c,d> -s <'command string, in quotes if it has spaces'>
+#
+# For example to read current time on different LCUs, all LCUs should report nearly the same time:
+#
+# python run_command_on_lcus.py --tel 2,5,6,8,9,c,d -s 'python $UPE/base/print_time.py'
+import sys
+import os
+import time
+import shell
+import common as cm
+import test_case
+
+tc = test_case.Testcase('RUN_ON_LCUs - ', '')
+
+lcu_str = 'Targetting LCUs: '
+LCUS = []
+for tel in tc.telStrList:
+ if tel == '':
+ continue
+ LCUS.append('lcu-rt' + str(tel))
+ lcu_str = lcu_str + ' lcu-rt' + str(tel) + ','
+tc.append_log(0, lcu_str[:-1])
+
+#tc.append_log(0, 'Wait for PPS')
+#cmd_str = 'python $UPE/peripherals/util_ppsh.py --unb 0 --bn 0 -n 4'
+#print 'cmd_str = %s' % cmd_str
+#shell.ssh_cmd(LCUS[0], cmd_str, tc)
+
+tc.append_log(0, 'Issue parallel command')
+cmd_str = tc.gpString
+for lcu in LCUS:
+ lcu_cmd = ['/usr/bin/ssh', 'ssh', lcu, cmd_str]
+ print lcu_cmd
