perl one liner to preserve line endings
In Perl, you can preserve line endings while processing a file using the -p
option, which automatically reads the input file line by line and applies the specified code to each line. To preserve the line endings, you can simply print the lines without any modification. Here's the one-liner:
perlperl -pe '' input_file > output_file
Explanation:
-p
: This option enables the automatic line-by-line processing of the input file.-e ''
: This specifies an empty code block, which means no modifications are applied to the lines before they are printed.input_file
: Replace this with the name of your input file.output_file
: Replace this with the desired name of your output file.
This one-liner reads the input file line by line and prints each line without any changes, effectively preserving the line endings in the output file.
Please note that Perl one-liners may have different behavior on Windows and Unix-based systems due to differences in line endings. If you're working with text files that use different line ending conventions, you might need to handle the line endings explicitly to ensure consistency. For example, you can use the -0777
option to slurp the entire file and then use regular expressions to convert line endings as needed.
