In order to make it easier for translators, the #. e2fsprogs po template file has been enhanced with e2fsck/scantest.c:109 #: e2fsck/unix.c:1010 e2fsck/unix.c:1093 @-expanded: Error while iterating over blocks in inode %i: %m\n c-format msgid "" "Syntax error in e2fsck config file (%s, line #%d)\n" "\t%s\n" msgstr 

In this tutorial, we will go through following topics. Example – Iterate over elements of an Array; Example – Consider white spaces in String as word separators; Example – Consider each line in string as a Remove blank lines (not including lines with spaces). grep . file.txt Remove completely blank lines (including lines with spaces). grep "\S" file.txt Note: If you get unwanted colors, that means your grep is aliases to grep --color=auto (check by type grep).
