Haven’t used these for years (mostly from uni):
basic, c, fortran, cobol, pascal, DOS-batch
More recently:
java, perl, python, golang, php, javascript, powersmell, xslt
Nobody has mention shell/bash. Doesn’t it count? I still use it every day, sometimes twice or three times a day.
grep awk sed ldapsearch find xargs read while ls chmod curl rsync ssh git etc etc
Update: I keep remembering other languages I’ve used. Z80 assembly, intel x86 assembly, DCL (OpenVMS scripting), tcl (as in expect)
