# If you want to edit the file in-place sed -i -e ‘s/^/prefix/’ file # If you want to create a new file sed -e ‘s/^/prefix/’ file > file.new If prefix contains /, you can use any other character not in prefix, or escape the /, so the sed command becomes ‘s#^#/opt/workdir#’ # or ‘s/^/\/opt\/workdir/’

Many UNIX-like operating systems have a basename executable for a very similar purpose (and dirname for the path): pax> full_name=/tmp/file.txt pax> base_name=$(basename ${full_name}) pax> echo ${base_name} file.txt That unfortunately just gives you the file name, including the extension, so you’d need to find a way to strip that off as well. So, given you have … Read more
Use curl –data-urlencode; from man curl: This posts data, similar to the other –data options with the exception that this performs URL-encoding. To be CGI-compliant, the <data> part should begin with a name followed by a separator and a content specification. Example usage: curl \ –data-urlencode “paramName=value” \ –data-urlencode “secondParam=value” \ http://example.com See the man … Read more

If you happen to reload the same page too often, post successive comments too quickly, or something else that triggers an alarm, make them prove they’re human.

Here is the script I used to find/replace all instances of text in a file: powershell -Command “(gc myFile.txt) -replace ‘foo’, … Read more
You can use __file__ to get the name of the current file. When used in the main module, this is the name of the script that was originally invoked. If you want to omit the directory part (which might be present), you can use os.path.basename(__file__).
It’s a convention so the *nix shell knows what kind of interpreter to run. For example, older flavors of ATT defaulted to sh (the Bourne shell), while older versions of BSD defaulted to csh (the C shell). Even today (where most systems run bash, the “Bourne Again Shell”), scripts can be in bash, python, perl, … Read more
