Well kind of... \u00a0When you are used to working in Python or any real language then Bash arrays are pretty lame. \u00a0But it can help in a few circumstances when you have to use Bash.<\/p>\n

\r\n# cat bash_array.sh\r\n#!\/bin\/bash\r\n# Array pretending to be a Pythonic dictionary\r\nARRAY_DETAILS=( "10.51.20.63:Host1:Solaris"\r\n                "10.51.20.80:Host2:Linux"\r\n                "10.20.50.11:Host3:Windows" )\r\n\r\nfor hostDetails in "${ARRAY_DETAILS[@]}" ; do\r\n  arrIN=(${hostDetails\/\/:\/ })\r\n  IP=${arrIN[0]}\r\n  NAME=${arrIN[1]}\r\n  TYPE=${arrIN[2]}\r\n  printf "Hostname %s with IP %s and is type %s.\\n" "$NAME" "$IP" "$TYPE"\r\ndone\r\n<\/pre>\n
And the result looks like this:<\/p>\n
\r\n# .\/bash_array.sh\r\nHostname Host1 with IP 10.51.20.63 and is type Solaris.\r\nHostname Host2 with IP 10.51.20.80 and is type Linux.\r\nHostname Host3 with IP 10.20.50.11 and is type Windows.\r\n<\/pre>\n","protected":false},"excerpt":{"rendered":"
