Full Discussion: VI command "line too long"
Top Forums UNIX for Beginners Questions & Answers VI command "line too long" Post 302977241 by Don Cragun on Friday 15th of July 2016 03:22:36 AM

By definition, text files meet all of the following requirements:
  1. the file does not contain any NUL characters,
  2. every line in the file is terminated by a <newline> character, and
  3. no line in the file (including the terminating <newline> character) contains more than LINE_MAX bytes.
On many systems, LINE_MAX is 2048. The value on your system can be determined using the command:
Code:
getconf LINE_MAX

The message you are getting probably indicates that the file you are trying to edit is not a text file because it violates requirement #3 in the list above.

If you want to split long lines in a file into shorter, adjacent lines that meet the requirements of a text file, try using the fold utility. If you want to split long lines into segmented files where one file contains the 1st X characters from each line from an input file and another file contains the X+1st through the 2Xth character from each line from an input file, etc.; try using the cut utility.

Without knowing more about the format and contents of the file you are trying to edit and the changes you want to make to that file, it is hard to suggest anything more specific.

NAME
logjam - GTK+ client for LiveJournal SYNOPSIS
logjam [OPTIONS] [FILE] DESCRIPTION
logjam is a GTK+ client for LiveJournal-based sites such as livejournal.com. Aside from writing entries, logjam lets you modify your friends list, edit your previous entries, and more. When run with no arguments (or just username option), logjam will run in the GUI mode. The user interface is mostly self-explanatory, and won't be discussed here in detail, except for a few notes below. OPTIONS AND COMMANDS
Options can be given in either short or long forms. For help on a particular commands, type "logjam COMMAND help". For example, "logjam grep help" will supply help about the grep command. Options: -v, --version Show version of program. -q, --quiet Say less. -u, --username=USERNAME Username to operate as. -p, --password=PASSWORD Password for the current user. -a, --postas=USERNAME User/community to post as. -f, --file=FILE File to load. -e, --edit Use default editor to edit post. Subcommands: checkfriends Efficiently check friends list for updates. console Run a command on the LiveJournal console. post Post event immediately. offline Manage offline copies of your journal. user Manage user list. Also, GTK+ command line options (such as --display) can be used. GUI
This section describes some of the GUI features that aren't immediately apparent. Check Friends logjam can monitor your friends list and notify you when new entries are posted there. Enable this by right-clicking on the indicator at the bottom-left corner of the application window and selecting the appropriate menu item. You may also configure logjam to start doing this automatically for you when you login. When new entries are detected, the indicator will turn red to let you know; click it to resume monitoring or double-click it to open your browser on your friends page. Optionally, you can have logjam open a small "floating" indicator which has some useful GUI settings of its own. Owners of large friends lists may prefer to be notified only after they accumulate several new posts. You may set the threshold for this in the Check Friends settings tab. The default is 1, that is, logjam will tell you immediately when it detects new traffic on your friends page. There is a small limit on the maximum threshold allowed, because this feature is only useful with small threshold values. STARTUP
When given a FILE argument, logjam will start up with an existing file as the base for the composed entry. If the filename given is "-", the data will be read from standard input. Several aspects of the entry, such as its subject field and the journal in which to post it to, can be controlled by other options. This is useful in conjunction with the --commandline option, which causes logjam to post an entry without going to GUI mode, allowing completely non-interactive posts. If you do wish to interactively edit the entry, but don't want to load the GUI, use the --edit option. Autosave logjam will periodically save a draft of your currently edited entry in ~/.logjam/draft if you turn on the draft option in the Preferences dialog. This feature is intended for crash recovery, not archiving. If you want to keep a copy of your posts, you should use the Entry > Save As menu option before submitting them. A future version of logjam will support archiving of your journal. Please note that when you exit the client normally, your draft is cleared. It does not "stick" for the next invocation, as in the behavior of some other clients. Checking friends from the command line You can use logjam as a backend for a script or another application that wishes to check the friends view. This may be useful if you don't want to use the GUI, or if you have several journals (in conjunction with --username). To do this, invoke logjam once with --checkfriends=purge (-rpurge if you're using short options), and then something like: logjam --checkfriends && new-entries-handler Make sure that your script or application purges the checkfriends status as described above once the user has acknowledged the new items, otherwise logjam will always report there's nothing new. You should also pay attention to limiting your query rate, despite the fact that logjam will refuse to flood the server with queries. For more information, see the messages on the command line. (To suppress these messages, use --quiet.) SEE ALSO
