I have a shell script that I have written to be a kind of to-do/notepad that's quickly executable from the command line. However, special characters tend to break it pretty well.
Ie: "notes -a This is an entry." works fine.
"notes -a This is (my) entry." will toss back a bash syntax error on... (5 Replies)

Heyas
Figured me had a 'typo' in tui-conf-set, i went to fix it.
Now, i also figured, it might be nice to have tui-conf-set report (to console, not only exit code) wether it could save the variable to the file or not.
This said, I appended this code: (the tui-title and tui-echo lines are... (3 Replies)

adsl-connect
ADSL-CONNECT(8) System Manager's Manual ADSL-CONNECT(8) NAME
adsl-connect - Shell script to manage a PPPoE link SYNOPSIS
adsl-connect [config_file] adsl-connect interface user [config_file] DESCRIPTION
adsl-connect is a shell script which manages an ADSL connection using the Roaring Penguin user-space PPPoE client. If you omit con- fig_file, the default file /etc/sysconfig/network-scripts/ifcfg-ppp0 is used. If you supply interface and user, then they override the Ethernet interface and user-name settings in the configuration file. Note that normally, you should not invoke adsl-connect directly. Instead, use adsl-start to bring up the ADSL connection. adsl-connect first reads a configuration file. It then brings up a PPPoE connection. If the connection ever drops, a message is logged to syslog, and adsl-connect re-establishes the connection. In addition, each time the connection is dropped or cannot be established, adsl- connect executes the script /etc/ppp/adsl-lost if it exists and is executable. The shell script adsl-stop causes adsl-connect to break out of its loop, bring the connection down, and exit. TECHNICAL DETAILS
adsl-connect uses the following shell variables from the configuration file: ETH The Ethernet interface connected to the ADSL modem (for example, eth0). USER The ADSL user-id (for example, b1xxnxnx@sympatico.ca). PIDFILE A file in which to write the process-ID of the adsl-connect process (for example, /var/run/pppoe.pid). Two additional files ($PID- FILE.pppd and $PIDFILE.pppoe) hold the process-ID's of the pppd and pppoe processes, respectively. By using different configuration files with different PIDFILE settings, you can manage multiple PPPoE connections. Just specify the con- figuration file as an argument to adsl-start and adsl-stop.
