Unix Tip #4187- July 29, 2012
PERL FIND AND REPLACE
In UNIX environment, the
following combination of perl
and find will serch for a
particular file and replace
the occurence of a particular
string with another string in
that file. This will also
work for multiple files and
directories. The find
command finds the file and
the perl script replaces
old string with the new one.
At the command prompt give
this command:
# perl -pi -e 's//' `find . -name ""`
NB: Perl should be in the
path and the general regular
expression rules apply while
using special characters
for eg / or .
