From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

# find with grep
# + concatinates results and runs the command once, faster
find . -name "*.txt" -exec grep -l "somename" '{}' '+'

# run a command for each result individually
find . -name "*.txt" -exec basename '{}' \';' |  column

# case insensitive
find -iname "SoMeNaMe.TxT

When using both {} and ;, it’s safer to use single quotes to escape the current argument and ending delimiter; eg ’{}’ and ’;’, respectively.

Why? The quotes will be consumed by the shell when you execute the command, unless you do like "'{}'"

Why?

Short answer: shell expansion.

Longer answer:

Executing a command for each file

• Run file on every file in or below the current directory.

$ find . -type f -exec file '{}' \;

Notice that the braces are enclosed in single quote marks to protect them from interpretation as shell script punctuation. The semicolon is similarly protected by the use of a backslash, though single quotes could have been used in that case also.
