Pipes with the < and >> meanings.

Hey,

Well, we're starting scripting next week for my class, and I have my command done, but I don't actually understand what the meaning is, so I was just wondering if someone could "translate" this in to words so that I might be able to do this better...

Quote:
c1 | c2 | c3 < inputInfo.txt >> outputCollection.txt


command1 | command2 | command3 etc.

But yeah...

Also, the command I have now, I was wondering if their is a way to get the output of the pips to work on 2 commands rather than just one...

Like, if I had ps -A | grep [numbers] | then have this pipe to both, wc and sort, so I can get the total amount of processes and have it sorted...

Sorry for multi-questioning, I really only care about the translation though,

Thanks so much!

Refer to smd-config(5) for a longer discussion on translators. Supported modes follow. oimap-dovecot This mode is designed to make the transition of offlineimap users to smd simpler. It assumes remote mailboxes are named like in the follow- ing: Maildir/cur Maildir/.sub.folder/new The corresponding local mailboxes are named like in the following: Mail/cur Mail/sub.folder/new nodots This mode simply gets rid of all dots. It assumes remote mailboxes are named like in the following: Maildir/cur Maildir/.sub.folder/new The corresponding local mailboxes are named like in the following: Mail/cur Mail/sub/folder/new move This mode just replaces the root of the mailbox, i.e. substitutes MAILBOX_LOCAL for MAILBOX_REMOTE and viceversa. USAGE IN CONFIGURATION FILE
Assuming the MAILBOX_LOCAL configuration variable is set to Mail and the MAILBOX_REMOTE is set to Maildir, one can use the following con- figuration file snippet in ~/.smd/config.endpoint: TRANSLATOR_RL="smd-translate -m oimap-dovecot -d RL endpoint" TRANSLATOR_LR="smd-translate -m oimap-dovecot -d LR endpoint" To test your setup use the smd-check-conf(1) utility. OPTIONS
