General :: Spaces In Command Line Switches

Oct 6, 2010

I am trying to encode files via mencoder. The file name has spaces in it. "test file.mkv". When I manually type the command in the terminal, everything works. But when I use a bash script (I'm reading it from a file) it doesn't. It gives me

Code:
File not found: '"test'
Below is the bash script I wrote

Code:
#!/bin/bash
# For testing, we have already built a file list, so just use that.
# ls *.mkv>files.lst
exec 10<files.lst
let count=0
while read -u 10 FILE; do
LINE="mencoder -of lavf -lavfopts format=mp4 -vf scale=1024:-3 -ovc x264 -x264encopts crf=28:vbv_maxrate=1500:nocabac:global_header:bframes=0 -oac faac -faacopts br=160:mpeg=4:object=2:raw -channels 2 -srate 48000 "$FILE" -o test.mp4"
echo $LINE
exec $LINE
done

exec 10>&-
files.lst contains only a single line (no newline) with
Code:
test file.mkv

On a related note, when I was first trying this simply on the command line, I had a file that had a double exclamation point. I found out that that is a shortcut of some kind for the previous command. My kludge to get around this was to try to execute a single exclamation point as a command, then to change the double exclamation point to a quadruple exclamation point. Is there a proper way (escape sequence or something) to pass double exclamation points to a command?

General :: Access Command-line Tty1 With Ctrl-Alt-F1?

Jun 14, 2011

I have Red Hat 5.4, and I'm trying to log in using tty1 by pressing Ctrl-Shift-F1. I get to the text login screen, my banner displays, but when I try to log in as root, the banner just displays again and it asks me to log in.

It does not say that my password is incorrect, just asks me log in as if the previous exchange never happened. I have added tty1 to /etc/securetty, and all the other tty's and vc/1, vc/2, etc...in an attempt to get something to work. I recently started using PAM for password authentication, and the pam_securetty.so line is set correctly in /etc/pam.d/login. Any idea why I can't log in? Did I miss something I have to add?

General :: Joining Two Files From The Command Line?

Oct 21, 2010

I'm looking for a solution for the following simple problem. I have two files, fileA and fileB. Each file contains only one word per line, and they contain exactly the same number of lines. I would like to create a new file called fileAB, where the i-th line contains the i-th line of fileA, a Tab separator character, and then the i-th line of fileB. I know how to do it in Python or other scripting languages, but it would be nice to have a bash one-liner for that. Is it possible to do this in bash or any other Unix shell, using the tools that are usually available on the command line (e.g., sed, awk and such)?

General :: Delete Files On The Command Line With Regular Expressions?

May 6, 2010

Lets say I have 20 files named FOOXX, where XX is the number of the file, eg 01, 02 etc. At the moment, if I want to delete all files lower than the number 10, this is easy and I just use a wildcard, eg rm FOO0* However, if I want to delete specific files ina range, eg 13-15, this becomes more difficult. rm FPP[13-15] does not work, and asks me if I wish to delete all files. Likewse rm FOO1[3-5] wishes to delete all files that begin with FOO1 So, what is the best way to delete ranges of files like this? I have tried with both bash and zsh, and I don't think they differ so much for such a basic task?

General :: Bash Command To Remove Spaces

Sep 14, 2010

I am reading the output of /proc/acpi/thermal_zone/ATF0/temperature in a program to read my CPU temp. I am using cat like the following:

Code:
#cat /proc/acpi/thermal_zone/ATF0/temperature
temperature: 49 C

I basically want to get rid of the spaces in between temperature and the actual temperature. Is there a command I can pipe the cat output to, to remove the spaces. I have seen suggestions for sed, or tr, but for some reason I cannot get them to work properly.

General :: Shell - Rename A File From Something Without Spaces To Something Containing Spaces?

Jan 26, 2010

Is it possible, in Linux, to rename a file from something without spaces to something containing spaces? I know I can create directories and files with spaces by doing:

mkdir "new dir" and:

touch "new file.txt"

I want to rename files from:

imgp0882.jpg to something like:

20091231 1243 some topic.jpg

And how would it look in a shell script that uses parameters like:

for i in *.jpg do
rename "$i" "$somepath/$mydate $mytime $mytopic$extension"
?

I'm new to Linux (using PCLinuxOS 2009.2), coming from Windows, and I've written myself a little shell script to download files from my camera and then automatically rename them according to a date-and-topic pattern. As you can guess by now, I'm stuck on the bit about renaming. If you want to see my script, here's a copy. I'm not using jhead for this renaming because that only works with JPEG files but I want a single solution for any media format including videos.

Ubuntu :: Command Line To Copy Files From One Location To Another / Retain Source Files Group / User?

Feb 20, 2011

Is there a method at the command line to copy files from one location to another and retain the source files group and user?I'm migrating some MySQL files from one machine to another.I want to back-up the original files in the directory presently. They have owner:group of mysql, some have owner:group root:mysql and so on. To copy them under cli or Nautilus everything changes to root for I execute sudo cp or gksudo nautilus and copy via gui.

Since it is MySQL data I could simply do a dump of the database and restore it on the other machine. But there's about 20 db's and I want to do this via a copy for it will be faster - at least that is what I think.

Fedora :: How To Access The Grub Or Command Line

Dec 18, 2009

with that said i burned fedora 8, 10, and 11 checked the sha1 verified everything was fine i had originally installed fedora 8 on an old pc i had from windows XP without any problems messed with it some, upgraded to 10 again no problems. tired to update 11 got a message about ext3 not found ext4 not found, re installed 10 the loader loads up now i have a blank screen with a cursor it the left hand corner

again i had 10 installed fine prior to all this can any one point me in the right direction to solve this issue or am i way over my head trying to figure this stuff out. i have spent 3 days searching these forums.

i'm just not quite sure what i need to do. oh, i tried to install 8 again and it wouldn't take either. i think the 10 problem has something to do with the graphic driver it's a geforce 7400 nvidia and something to do with the grub, but like i said i get a blinking cursor and not quite sure how to access the grub or command line.

Fedora :: Access Machine In Command Line Mode

The "f" is how I now feel.I do "fn+f2" as it is booting and it displays the sequence of loading items which report all is "ok" until it gets to "jexec services" and then it hangs.I do not know how to access the machine in command line mode and I am not sure what to do from here. I beleive the "jexec service" is a Sun Java item but I am not sure.

Programming :: Pad End Of Each Line With Spaces To = 80 Chars?

Apr 14, 2011

I've searched the forums and the google looking for a means to do this and haven't found anything I can use. I have a large file that looks like this:

Code:

18000034161828M850
18000034172676M850
98 093095

[code]...

I need to add spaces at the end of each line to ensure that every line has 80 chars before the carriage return. I was thinking something like this, but it doesn't do the right thing:

Code:

cat filename | sed -e 's/$/(bunch of spaces)/' | cut -c1-80 > filename2

I'm on fedora, so I can use awk, sed, bash, ksh, etc.
