Replace a given word with a new one from a set of files - Here, I'm replacing the word 'oldWord' with 'newWord' of a set of files that ends with .xml in the current folder.

find . -name "*.xml" -exec sed -i "s/oldWord/newWord/g" '{}' \;

to replace the word "<webXml>${basedir}/../../web.xml</webXml>" with newWord. Note the escape charater (\) before $ and /. Used : for easy writing.

find . -name "pom.xml" -exec sed -i "s:<webXml>\${basedir}/../../web.xml<\/webXml>:newWord:g" '{}' \;

Only copy a set of symbolic links in the current directory, and copy those to a separate folder. I did this in Ubuntu.
cp `l -1 | grep -ri @ | grep -ri "[^@]*" -o` ../my-symlinks/ -P

l -1 | grep -ri @ | grep -ri "[^@]*" -o - Selects outputs the file names of the symlinks. Then we copy it using cp with the parameter -P. -P means that cp won't follow the symlinks.

Bash for loop - in one line

for file in `fn pom.xml`; do echo $file; done
