(If you are using bash 4, scroll to the end for what I think is the best combination of pure shell and readability.) For heredocs, using tabs is not a matter of preference or style; it’s how the language is defined. usage () { ⟶# Lines between EOF are each indented with the same number … Read more
If you want to extract the files to the respective folder you can try this find . -name “*.zip” | while read filename; do unzip -o -d “`dirname “$filename”`” “$filename”; done; A multi-processed version for systems that can handle high I/O: find . -name “*.zip” | xargs -P 5 -I fileName sh -c ‘unzip -o … Read more
Simple replacement with sed is okay but not the best possible solution. If there are “extra” spaces between the tabs they will still be there after substitution, so the margins will be ragged. Tabs expanded in the middle of lines will also not work correctly. In bash, we can say instead find . -name ‘*.java’ … Read more
Taking advantage of str.split’s behavior with no sep parameter: >>> s = ” \t foo \n bar ” >>> “”.join(s.split()) ‘foobar’ If you just want to remove spaces instead of all whitespace: >>> s.replace(” “, “”) ‘\tfoo\nbar’ Premature optimization Even though efficiency isn’t the primary goal—writing clear code is—here are some initial timings: $ python … Read more
Ok, this is not simply an update but also an answer so I’m filing it as one. According to all information I could find, the following should theoretically do it: String[] cmd = {“explorer.exe”, “/select,\”C:\New”, “”, “”, “”, “”, “”, “”, “Folder\file.txt\””}; The multiple spaces have been broken into empty strings and the array version … Read more
String.split() will do most of what you want. You may then need to loop over the words to pull out any punctuation. For example: String s = “This is a sample sentence.”; String[] words = s.split(“\\s+”); for (int i = 0; i < words.length; i++) { // You may want to check for a non-word … Read more
Late to the party but… There is no need for iteration through cells/values nor a recursive function to search and replace multiple spaces in a range. Application.Trim wil actually take care of multiple spaces between words (and will trim leading/trailing spaces) leaving single spaces in between words intact. The great thing about it, is that … Read more
Spaces are not treated as equivalent to tab. A line indented with a tab is at a different indentation from a line indented with 1, 2, 4 or 8 spaces. Proof by counter-example (erroneous, or, at best, limited – tab != 4 spaces): x = 1 if x == 1: ^Iprint “fff\n” print “yyy\n” The … Read more
Execute it like this: “$VAR”. This is one of the most significant gotchas in shell scripting because strings are always substituted literally and any contained spaces are treated as token delimiters rather than as characters of the string. Think of substituting a variable as a kind of code pasting at runtime. What really happens when … Read more
” “.join(my_list) You need to join with a space, not an empty string.
