General :: Copy Command Output In Vim?

Jul 25, 2010

For example, if I type ':pwd' to get the current working directory, I can select the text in gvim but I can't figure out how to copy it to the clipboard. If I try the same in console vim, I can't even select it with the mouse. I would like this to work with all vim commands, such as set guifont to copy the guifont=Consolas:h10:cANSI output.

General :: Copy A Read-Only File And Make The Copy Writable With A Single Cp Command?

Mar 1, 2011

How to copy a Read-Only file in Linux and make the copy writable with a single cp command in Linux (Ubuntu 10.04)? The --no-preserve and --preserve seemed to be good candidates, except that they should "and" the mode flags, while what I am looking for is something that will "or" them (add +w mode).

More details: I have to import a repository from GIT to Perforce. I want that all Perforce depot files are Read-Only (that is how Perforce was designed), while all other files that were derived/copied from depot files are writable. Currently if a Makefile tries to copy a Read-Only file then the derived file will also be Read-only. This leads to build-errors when cp tries to overwrite Read-Only file second time. Of course the --force is a workaround here but then the derived file is also Read-Only. Also I do not want to mess with "chmod" after each "cp" command - I will do that only as the last resort.

General :: Copy / Paste Output From Shell (not Terminal)?

Jul 15, 2010

I often have issues starting my window manager--xfce. My computer misbehaves in one of 3 ways, one of which is to fail to open X, but generate several screens of info. I want to paste that info to this site, but since I'm in the shell, not the terminal (please correct my vocabulary if it's wrong here), I don't know how to copy and paste the output, since right-clicking doesn't give me a menu. Even if I could copy I'm not sure the information would be accessible in X. Are there any other options?

General :: Copy Previous Output From Bash Terminal To File?

Oct 26, 2010

I know how to redirect the output of a terminal to a file. For example, if I want to list all the files in ~/Documents and output to a file called test.txt, I would do this: ls ~/Documents > test.txt The question is, can I copy the output to test.txt AFTER I have carried out the command? This would mean that I wouldn't have to know in advance whether I want to copy the output to file. I want to do something like this: ls ~/Documents Then this: <bash command for copying standard output to test.txt>

General :: How To Truncate Command-Line Output

Sep 6, 2011

If I grep -nr sumthin * in my source code directory, it also spews out very long lines from minified JavaScript or CSS files. I want to get just the first 80 characters per line. For example, a regular grep gives me this:

css/style.css:21:behavior: url("css/")
css/style-min.css:4:.arrow1{cursor:pointer;position:absolute;left:5px;bottom:10px;z-index:13;}.arrow2{cursor:pointer;position:absolute;right:5px;bottom:10px;z-index:13;}.calendarModule{z-index:100;}.calendarFooterContainer{height:25px;text-align:center;width:100%!important;z-index:15;position:relative;font-size:15px!important;padding:-2px 0 3px 0;clear:both!important;border-left:1px solid #CCC;border-right:1px ... etc.

But I'd like to get just this instead:
css/style.css:21: behavior: url("css/")
What Linux command can do this?

General :: Redirecting Command Output To File?

Sep 19, 2011

This seems so simple when doing it from command line but I'm not able to accomplish it inside a script. I am trying to put output of following command into a text file:

CMD= mysql -uroot -psecret -e 'SHOW SLAVE STATUS G;'
FIL=~/replication-`date +%F`.txt
touch $FIL

Where FIL is a variable that contains path of the file to which to output command. I am running this command in a shell script from where I want to email contents of $FIL as attachment using mutt. But I am always getting 0 byte file. Also if I examine in directory the file is of 0 byte length.

General :: Evaluate Size Of Output Command?

Nov 18, 2010

I'm trying to do something like this:

cmd1=$(cat /var/log/messages | grep -e 'blocked for more than 120 seconds' | cut -c 55-62)
if $cmd1 != 0; then echo 'okay'; fi

however i'm messing up somewhere... bash attempts to evaluate the elements in cmd1. when I try to run this script it complains saying:

Quote: line 5: blocked: command not found

I am open to alternatives. My intent is to replace cat /var/log/messages with dmesg, so I can attempt to determine if a problematic application I use encounters a blocked state (unresponsive for more than 120 seconds).

Should I be using a different test condition? I tried something like:

# this declares cmd1 as an array
cmd1=($(cat /var/log/messages | grep -e 'blocked for more than 120 seconds' | cut -c 55-62))
#attempt to determine if number of elements in array is greater than zero
if ${#cmd1[@]} > 0; then echo okay; fi

But I get the same error... what am I doing wrong?
