To do this, add their titles to the list of Invariant Sections in the Modified Version’s license notice. These titles must be distinct from any other section titles. If the Modified Version includes new front-matter sections or appendices that qualify as Secondary Sections and contain no material copied from the Document, you may at your option designate some or all of these sections as invariant.

Hi Sohail,
i am getting this error while installing “yum -y install ntfs-3g”
Transaction check error:
file /usr/bin/ntfs-3g conflicts between attempted installs of ntfs-3g-2:2015. X86_64
file /usr/bin/ntfsmount conflicts between attempted installs of ntfs-3g-2:2015.

I’m using ${variable} here instead of $variable which isn’t supported under all shells but it is supported under bash. It’s not necessarily needed here however I prefer to use most of the time (there are some instances where you shouldn’t use it) because I consider it a safe way to protect against errors where perhaps part of the text is not part of the variable, for example, if my variable named num containing the number 5 and I want to echo “The 5th number” where I use the variable num for 5 then, if I wrote.

The ‘C’ locale is used if none of these environment variables are set, if the locale catalog is not installed, or if grep was not compiled with national language support (NLS). For example, if LC_ALL is not set, but LC_COLLATE is set to ‘pt_BR’, then the Brazilian Portuguese locale is used for the LC_COLLATE category. The first of these variables that is set specifies the locale. The locale for category LC_foo is specified by examining the three environment variables LC_ALL, LC_foo, and LANG, in that order. The shell command locale -a lists locales that are currently available. As a special case for LC_MESSAGES only, the environment variable LANGUAGE can contain a colon-separated list of languages that overrides the three environment variables that ordinarily specify the LC_MESSAGES category.

and so on. So it can be:

will match files which names start with a,b,c,d,e,f or g, then there are subsequent three characters – each dot (. ) represent any character – then there is r,s,t,u,v,w,x,y or z and then text.

A number which includes a decimal point). Assume the number is always surrounded by white space. 2) Use grep (or awk) to output all the lines in a given file which contain a decimal number (e. Decimal numbers do not have leading zeros but they might have trailing zeros.

Deb packages on your system. ” The –i option is there to ignore-case, as grep is case-sensitive. Using the –i option is a good habit of getting into, unless of course you are trying to nail down a more specific search. Second, we piped that output to grep –i python, which simple states “go to grep and filter out and return everything with ‘python’ in it. First, we ran dpkg –l, which lists installed *.

Specifying -U overrules this guesswork, causing all files to be read and passed to the matching mechanism verbatim; if the file is a text file with CR/LF pairs at the end of each line, this will cause some regular expressions to fail. Treat the file(s) as binary. This option has no effect on platforms other than MS-DOS and MS-Windows. If grep decides the file is a text file, it strips carriage returns from the original file contents (to make regular expressions with ^ and $ work correctly). By default, under MS-DOS and MS-Windows, grep guesses whether a file is text or binary as described for the –binary-files option.

4 on a CentOS Linux server. 10 which is super old but it is definitely not the latest stable release available. I have been needing to upgrade the PostgreSQL servers at my work for awhile now and was finally forced to do so after needing some of the features available with PostgreSQL 8. The full vacuum process, which is required to reclaim disk after deleting data from a table, in 8. Follow the directions below to first backup all of your PostgreSQL data, remove the current PostgreSQL installation, and then install PostgreSQL 8. Over the past two years I have become a lot more familiar with Postgres and one thing that has been disappointing is the downtime involved in reclaiming disk space via data removed from PSQL database tables. When you are dealing with large tables over 10GB in size this can take days to complete. One thing I am looking forward to testing is the improvements to the vacuum process. 3 requires a lock on tables which essentially causes downtime. Currently we are running PostgreSQL 8.

So the second line is more efficient and less to type :). Txt | grep ‘some text’
and
grep ‘some text’ file. Txt
do actually the same, with the difference that the first line uses an additional process, ‘cat’. Hi,
great article, just one smartass-necessity:
cat file.

Word-constituent characters are letters, digits, and the underscore. Select only those lines containing matches that form whole words. The test is that the matching substring must either be at the beginning of the line, or preceded by a non-word constituent character. Similarly, it must be either at the end of the line or followed by a non-word constituent character. This option has no effect if -x is also specified.
