General :: Linux Command Synopsis Notation?
Feb 1, 2011
I've recently started learning linux OS, and the most confusing for me is the notation in man pages or command synopsis. I was looking for some kind of guide describing it, but couldn't find any. Thing get even worse when there is no standard notation and it looks different from one command to another. In other words, I just want to understand what all these brackets '[ ]', dots like '...' pipelines '|', italic or UPPERCASE words, etc mean at all. I can't tell the difference between [DIRECTORY...] and [FILE]... What does it mean when there are three dots inside the brackets or outside of them? And so on. To conclude, all I need is a comprehensive description for the notation syntax adopted in linux world.

Is anyone aware of a program which will open .mus music notation files or convert them to .xml files? I have several files from FINALE which I would like to open in Linux, but Linux distros will not allow FINALE to run. .xml files will open in MuseScore.

'ls -l' gives me the permissions in the long format - drwxr-xr-x format. Is there a way i can get the permissions in a form i can use in a bash script? the only form i can imagine of is the octal one... something like '755' for the above, but i dont know what would give me such an output.... are there other methods to consider while using (rather comparing) them in a script?

I have written a set of aliases in a file.When i tried to dot it( "Prompt> . filename" ). It said " Permission denied. "But, when I sourced it ("Prompt> source filename"). It worked perfectly.Linux manual has one entry for both the commands. Then what am I missing ?

I have some checksums.md5 verification files from an ntfs external drive, but using windows notation: instead of /, spaces between file names (not escaped), reserved shell characters (like (, &, ', to name a few). The checksums.md5 has a bunch of checksums and filenames:
[code]...
I want to use this checksums.md5 to verify the files that I've copied to my machine: but I'm on a Linux, so I need to convert the names inside checksums.md5 from Windows to Linux to use the md5sum utility from the shell. The first line in my example would become: f12f75c1f2d1a658dc32ca6ef9ef3ffc My Windows & Files (2010)/[bak]/testing.wmv Is there some application for this (converting a file listing, from windows cmd notation, to linux shell notation) or will I need to create a bash script using sed that just "replaces" what is "wrong" with the filenames

I'm trying to figure out how to change the tomboy saving notation (.note) to (.txt). I'm fairly new to Linux so I may be wrong in thinking this is possible. However, if it is possible, a finger in the right direction would be appreciated.
PS: if it isn't possible, maybe there is a way to change the name of the actual .note files in ~/.local/share/tomboy/ to something more readable. Right now they show up like this:
8e824ab7-ba6f-4018-b74d-1a5a245a60bd.note Which is of course makes it difficult to determine which file I'm actually looking at.

I've been away from Fedora for a long time, since FC3/4. I seem to recall that at that time grub in Fedora used the standard drive notation such as /dev/sdax instead of the current UUID. Can anyone tell me why this change was made?
Seems to me that using UUIDs presents severe problems if a drive has to be replaced as the restore media (we all backup, don't we?) would not work without modification. How does one determine trhe UUID of a new drive to change the restore media? Sounds like a chickenand-egg routine. There must be some way which I haven't run accross yet. I do notice through experimentation that the standard notation still works, at least in /etc/fstab.

I have learnt that the network locked huawei modems may be unlocked to use any sim card bu getting a special unlock code and it should ask for it when a "foreign" SIM card is inserted. This procedure works well in Windows, but in Linux where I use wvdial, I dont get prompted for this unlock code. Does anyone know how to insert the unlock code in Linux using any Linux tool (GAMMU/GNOKII/Minicom etc)?

I may not have noticed in other Fed releases, but in Fed 13 I am seeing a dot at the end of all file permissions. Example:
[pjs@linux ~]$ ls -ld Documents
drwxr-xr-x. 62 pjs pjs 4096 Jul 11 09:53 Documents
Even on files I create myself:
[pjs@linux ~]$ touch foo
[pjs@linux ~]$ ls -l foo
-rw-rw-r--. 1 pjs pjs 0 Jul 11 10:46 foo
It is the same throughout the fs. I have disabled as much of SELinux as I can. What does the dot mean?

I am working on a friend's computer for which he "lost" the operating system. This friend has very little extra money right now, so my classmate suggested I try loading Linux on my friend's PC.I am wondering if it will work. The PC is a Compaq Presario SR5610F with an AMD processor. I have been told that Linux doesn't care much for AMD.Does anybody know if it will be possible to use Linux as an OS on this PC?I'm looking for a cheap(er) alternative than Windows. Friend is balking at Windows 7. The machine had Vista loaded in it when purchased, then the son loaded XP on it, without removing Vista. They have been having issues with crashing for some time now. The recovery disks are supposed to have XP on them, but I don't think that is so, and when I tried running those disks, the computer balked. I finally worked around and got XP to install, using a disk from an old computer, but the code would not work, and nobody could remember the computer's password and user name.I want to start fresh with this machine, and install a basic, working OS. Am leary about XP on eBay or some such, but they really don't have the funds to purchase anything over $100.00.

I have a netbook, L500X Geode (498MHz) 480Mb Ram and 40Gb Hdd partitioned into two 20 Gb bits, and I want to install linux on it as a dual boot along side the winxp that is already in place. I tried the Netbook remix of the latest Ubuntu and Fedora 12 with no success at all. I'm beginning to wonder if this tiny old machine can run linux at all.
