I use the potion :a. I have launched some 8 different Singular commands in 8 different shells. I want them to write all in the same file. Is there risk that they write in the same time and the output is gibberish? Or does each of them lock the output file while it writes in it? Danke schön. |

That is very dangerous: if the files are opened with mode ":a", all output goes to the same file in undefined order, producing gibberish. If the files are opened in mode ":w", all output but that from the last opener disappears. |
