I have a line like
port = 2566
I want to replace it as
port = 8080
how to do this in shell script. when i tried to do this with sed
sed -i 's/port=.*/port='$3'/' /root/$2
it is not recognizing spaces , it works only if line is port=2566 .
I have two files, file1.traj and file2.traj. Both these files contain identical data and the data are arranged in same format in them. The first line of both files is a comment.
At line 7843 of both files there is a cartesian coordinate X, Y and Z ( three digits ). And at line 15685 there is another three digits. The number of lines in between two cartesian coordinates are 7841. And there are few hundreds of thousands of lines in a file.
What I need to do is copy the X Y Z coordinate (three digits) from file1.traj at line 7843 and paste into file2.traj at the same line number as in file1.traj. The next line will be 15685 from file1.traj and replace at line 15685 at file2.traj. And I dont want other lines (data) in file2.traj get altered. This sequence shall be going on until the end of the file. Means copy and substitude the selected lines from file1.traj into file2.traj.
I tried to use paste command but I cant do for specified line alone.
Here i showed the data format in the file. I used the line number for clarity purpose.

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

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?

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.
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:

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/$/(bunch of spaces)/' | cut -c1-80 > filename2
I'm on fedora, so I can use awk, sed, bash, ksh, etc.
I'm trying to insert a line using sed that has leading spaces before the text. Sed seems to be just dropping the spaces and only inserting the text. Any ideas what I'm missing?
Code:
NAM=rb134
sed -i.bak -e "$i
host ${NAM} {" /etc/crap
Instead of inserting a line with 8 leading spaces inserts it with "host" at the beginning of the line. I tried
Code:
NAM=rb134
sed -i.bak -e "$i
^ host ${NAM} {" /etc/crap
but it put the "^" at the begging of the line.
Does any one know what syntax i could use to allow me to replace all instances at the beginning of a line with ones.

I've got a file that I want to convert to a CSV format.
Each line of the file is something like:
term1a term1b [pronunciation] definition
term2a term2b [pronunciation] definition
term3a term3b [pronunciation] definition
To get it into CSV, I just need to perform 3 find and replace operations:
First, replace the first " " (space) with a "," (comma). Next, replace the first " [" (space and right-facing square bracket) with a "," (comma). Finally, replace the first "] " (left-facing square bracket and a space) with a "," (comma).
The reason it must only be the first such occurance, is the definition area contains lots of spaces and square brackets which I'd like to leave left untouched.
I would like to replace 'xxxx' with 'yyyy' which is in a file xyz.csproj not sure of what 'xxxx' is, it can be 3055, 4056, 7089 etc. I know it always appears at line # 5 and at character 50.

I'm trying to use a tilde '~' for a filename. This works fine normally Code: rm ~/File
But when I have a file with a space in in and enclose it in quotes it takes it literally.If a word begins with an unquoted tilde character (�~�), all of the characters up to the first unquoted slash (or all characters, if there is no unquoted slash) are considered a tilde-prefix.
A process with name=example can be killed by killall -9 example

View 2 Replies View RelatedI 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.
I did the following script:
Code:
DIR=`pwd`;for i in `find . -name GESTION -type d`;do cd $i/..;setfacl -R -m g:directores:rwx,
GESTION;echo $DIR'/'$i;cd $DIR;done
This code do the following actions:
1. Starting inside a folder, it's searching for any folder called "GESTION"
2. Every time a folder called "GESTION" is found, then the script move to its parent folder, and then it applies ACL permissions to the folder GESTION by using the command setfacl.
The problem is that the script doesn't works when there was found a folder with a blank space in its name. I mean:
/dir1/dir2/dir3/GESTION --> this works fine
/dir1/dir2/dir 3/GESTION --> this doesn't works
/dir1/dir2/dir3/2. GESTION --> this doesn't works

I'm hoping that someone can help me, I need to remove spaces (not replace with underscores) from several thousand files on a system with cygwin.
Can I do this from the shell using rename or mv somehow?
need all spaces between two letters or a letter and a number exchanged for an underscore, but all spaces between a letter and other characters need to remain. One example for clarity:
Input:
force -- lamin 90 [label]
active A -- generation [label]
