Operating System: CentOS 5.4 I have a bash script that runs another php script to return a decrypted password. The return value is right but when I concatenate it with another string, I would not have the whole string. To better understand the problem, here is my script:
***********************************************************************************
#!/bin/bash

I want to match some filename in some text, but the filenames I have no control of, so "[" can "]" can appear in the filenames.so do I always have to use sed to addslashes to these variables before I have to grep them? and what other characters have I missed other than "[", "]", "."?

I need a script that will replace '/' in a variable with ''I have tried the following:
Code:
y=$(echo $1|sed 's///\/g')
The thing is that this approach does not always work. Here is an example:
Code:
user@pc:~$ sh script.sh /usr/var/sakis.txt
z:usr
arsakis.txt
user@pc:~$ sh script.sh /usr/tar/sakis.txt
z:usr arsakis.txt
Is there a way to treat those characters?

I have two systems at hand. One a Debian box, the other a RHEL5 box. On the Debian box there is a MySQL server (5.0.32-Debian_7etch1) running which hosts Databases from a customized content management system. This system has grown over time and the tables are stored with different collations. Now I want to export and reimport the data on the RHEL5 MysQL server (5.0.45).
And here the special character hell begins. It doesn't matter if I reimport the data as utf8, as latin1 or latin1_swedish_ci. Everytime the special characters are wrong and distorted. Surprisingly the data that is shipped with the unmodified CMS displays the special chars correctly after installation. But I have to import the modified version from the old server as there are lots of modifications to import.
Old server:
Quote:
character set client utf8
(Global value) latin1
character set connection utf8
[code]....
New server:
Quote:
character set client utf8
(Global value) latin1
character set connection utf8

I am reading strings from a file using readline() function,the file contains some strings which has only special characters, I need to avoid the strings which has only special characters, the special characters are not similar. How to do it in python.??
View 2 Replies View RelatedI am having difficulty getting sed to replace a string of text in an XML file, despite the fact that I have no trouble using grep to find that same string. Since the new string and old string to be replaced contain a lot of special characters, I thought it best to store them in variables as opposed to using a slew of backslashes:
OLD_STRING='<property name="webServiceHost">${jboss.bind.address}</property>'
NEW_STRING='<!--<property name="webServiceHost">${jboss.bind.address}</property>-->'

Below is extract of my file:
What I need is to replace "--destination-path=" with "--destination-path=/home/dest"
i.e. desired output is ----destination-path=/home/dest
I could achieve it with below command
$cat outgoing-xfer|grep destination-path|perl -pi -e "s/destination-path=/destination-path=/home/dest/g"
But the problem is that in this case i just wanted to append "/home/dest" for which I could easily escape "/" with just two "", but I wonder if i have a long path like "/a/b/c/d/e/f/g/h/i/j" I will have to escape so many /. Is there any other way by which I can avoid escaping forward slash.
I tried following:
But receiving follo error
Bareword found where operator expected at -e line 1, near "s/destination-path=/'destination-path=/home"
syntax error at -e line 1, near "s/destination-path=/'destination-path=/home"
Bad name after dest' at -e line 1. tried with enclosing in double quotes as well but in vain

View 3 Replies View RelatedI have a folder of MP3s, where some have <artist>- <song> and others have <artist> - <song>. I wanted to make all of them say <artist> - <song>
The command that works for me was
for i in *[a-Z]-*; do mv "$i" "`echo $i | sed 's/-/ -/g'`"; done
but if I -hadn't- used ls with my parameters to filter out the valid results, how would I have done this with sed? I got close with:
ls | sed -e 's/(.*)[a-Z]-(.*)/1 - 2/'
but with the above I lose the [a-Z] character that I used to match with (and I need to keep that).
I'm trying to retrieve a single string or value from /proc/cpuinfo, but when I try to extract the model (not the model name) the model name comes with it, also it likes to print it twice...

echo $model
All i want this to do is spit out the model number once. (I need to pass it to another script)
I have to enhance the behaviour of a backup script written in perl. I don't need to change it, what I need to do is to create a bash script that does some checks like file name and file size, execute the backup script then check if the backup files match the original files.Here's how I try to do it:
- read the files from the original files folder
- store them in an array
- search in the array the files that have a specific file extension
- store the file names that match the search pattern (I know the backup script skips some files so I can hardcode the search pattern)
- run the backup script
- read the files from the backup folder
- store them in an array
- compare the original files name and size stored in an array with those from the backup folder
- send a report email
Inside a loop i'm populating a string variable. Because csh doesn't have very good support for arrays I thought of doing this. I want to add a new line character to the end of the concatenation each time the loop iterates. Then at the end print this variable out.
I tried " and some resources said it was just a "". Neither work. What am I doing wrong?

View 9 Replies View RelatedI have searched and searched in regards to this documented 'special expression '-l STRING' for the 'test' command, and to no avail, have I found out why it does not work on my system.
The example always given is:
Code:
test -l abc -gt 1 && echo yes
And the returned result is:
Code:
bash: test: -l: unary operator expected
The documention is usually as follows:
Numeric tests
Numeric relationals. The arguments must be entirely numeric (possibly negative), or the special expression `-l STRING', which evaluates to the length of STRING. Then examples are given, including the one I provided above. Does anyone else have this issue of getting an error when trying this special expression of 'l STRING' ???

View 2 Replies View RelatedI am trying to install 5.3 using net install disc, where it hangs for over 30 minutes trying to retrieve stage2.img. Second time. After first time and waiting over 25 minutes, I tried Debian net install on another box, and it's done with installation long ago, while this one is still hanging (and from the looks of it I doubt it will continue).
1. Network is good, the box pings, network parameters are good, Debian worked flawlessly with same parameters
2. It did pull all it needed before stage2.img
3. Plenty of RAM in the box, over 3 GB
4. The box needs no additional drivers (except newer version of kernel as vanilla still doesn't have a complete support for Intel DP43TF board), distro has them all
