Im using this unix command(in a php file) to remove a certain string and then remove the whitespace left by that string. Unofrtunately in many cases, the files get completely erased. Is there a workaround?
Code
<?php
$dir = "./";
$rmcode = `find $dir -name "*.php"

I am trying to read a file character wise and trying to write the same character to another file. In this process, I unable to read and write white spaces successfully to the new file. The script reads the white spaces but while writing the white space is lost. The section of the code, is given below. Please advice how can i read and retain the white space while writing to a new file.
Code:
if [ -s f_test.txt ] && [ -f f_test.txt ]; then
echo "File Exists !!"
while read -n1 char; do

I want to match for this string:
Code:
Content-Transfer-Encoding:[:space:]base64
Content-Disposition:[:space:]attachment;[:space:]filename="%variable%"
Both lines are new lines, so they won't be inline. Other than that, they are all constants, I want this regex match to be an if statement rather than returning match string. so if the $content variable contains some string that matches:
Code:
if `sed "//p"` ;
here is what is in my file:

i have xterminus installed. i also have a white block over the first letter in my username and when i begin typing, the 'block-type cursor' just leaves full white spaces behind and i cannot read my text at all. even when i delete back over the white spaces, they stay whited out.
I have just switched to banshee as my media player and imported my films and music. Problem is, the video list is quite hard to read because all the video files have spaces in their names which are replaced by % signs, numbers and letters. I'm wondering if there is a command I can use in the directory that will automatically remove all the spaces from the filenames or better still, replace the spaces with hyphens or underscores?

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.

command to find list of table spaces in oracle in unix
View 1 Replies View RelatedWe switched from unix to linux and we have an old report that extracted data from a database, output to an ascii file and then sorted the results in the file based on different arguments. The report now blows up when it runs,and I can only guess it is because the options for sort on linux differ slightly from unix.For example, here is one of the commands issued from within the report app that ran on the old unix box:
if sort-sequence = "descending" then
'sort -t~" -f +3.0f -4.0 +5.0r -6.0 -f '
else
'sort -t~" +3.0f -4.0 +1.0f -2.0 -f'
I will eventually rewrite the report to store the data in a local table, but I can simply adjust the options to suit the requirments of linux. Basically, I need to know if this can be a quick fix for the short term.

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?

I tried solving this with sed but obviously s/ /_/g does not work, nor does any s/[a-zA-z0-9] [a-zA-z0-9]/[a-zA-z0-9]_[a-zA-z0-9]/g , because you just can't do this...
I want to delete all files within a specific folder without actually deleting the folder, what is a good bash command for this?. I found this one but encountered some errors even though I am executing it within the specific folder:
useratdebian:/home/user/folder# find . -type f -exec rm -rf {} ;
[1] 5052
useratdebian:/home/user/folder# find: missing argument to `-exec'
[1]+ Exit 1 find . -type f -exec rm -rf
The command as it appears is:
find . -type f -exec rm -rf {} ;
how to delete only the files contained within the folder called "folder" for example?

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

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

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?

I am tring to get the MAC address from windows xp and remove it from a file on a unix box. This is what I have so far:
getmac | plink.exe -ssh -pw "my pw" -noagent -m commands.txt root@192.168.1.82
commands.txt
cd /root
tr '-' ':' | tr -d '[:blank:]'
now this is what I get
10:9A:CD:5F:04:8ADeviceTcpip_{5A79FE8D:F227:4B91:9459:2701486C5D94}
All I need is the MAC. Everything after Device* is not needed.The file is /var/db/captiveportal_mac.db. The MAC address are listed like this.
MAC1
MAC2
MAC3
MAC4
MAC5
How do I access files with spaces from the command line?
for example I want to go to a file called "New File" and let's say is in Downloads/Books/(and here is the file)
how do I input the space since the command line doesn't recognize it?
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.

View 1 Replies View RelatedA simple TCP based chat server could allow users to use any TCP client (telnet, for example) to communicate with each other. For this question you should consider a single process, single thread server that can support exactly 2 clients at once, the server simply forwards whatever is sent from one client to the other (in both directions). Your server must not insist on any specific ordering of messages as soon as something is sent from one client it is immediately forwarded to the other client. As soon as either client terminates the connection the server can exit

Makefile:2: *** missing separator (did you mean TAB instead of 8 spaces?). Stop.
Should I give a tab or spaces not able to continue.
I have been trying to code a program in C++ that must check for the correct syntax in order to operate. It must find ", " within the string, but I don't know why the compiler won't recognizes spaces.
Code:
#include <iostream>
#include <stdio.h>
#include <string>
[Code]....
So the user must input "<name>, <interest>" with the ", " (comma and space) but even if you respect the syntax the compiler will skip to the else condition. I don't know why, but if I put any other condition like ",s" it will work, but not with spaces.
I have a file of the type:
a = b
where a is any string and b is an integer The 'a' string doesn't have any spaces in it.
Everything was running fine till I was searching for 'a' and finding value 'b' by expression
Code:
string="$a"
egrep -i -m1 "^[[:space:]]$string[[:space:]]*=" | awk -F'=' 'gsub(/^[[:space:]]+/,"",$2)gsub(/[[:space:]]+$/,"",$2){print $2}'
I recently ran into a situation where in the string 'a' had symbols like $, & in it. Though I haven't checked it for & but $ is definitely breaking my code
Any way to egrep for string with $ ??
One way I though was to replace every occurence of $ with $ in my search expression but that would involve an extra processing each time

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:

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