Auto-update program cache feature

Hi Everyone, I noticed a fair number of new Linux users have trouble with stale program caches. Users install a package from a package manager or sources and then are confused when the new package is not used. They do not realize they need to run 'bash -r'; and most don't know where to begin searc

How to tell Bash multiple values are success?

Hi Everyone, I have a systemd service that automatically applies updates. Looking at the service history, the service reports failure when it installs updates due to this: if dnf -y update &>/dev/null then echo "Upgraded system" else echo "Failed to upgrade system"

Create an alias on the fly?

Hi Everyone, I'm testing some software from Master. My testing machines sometimes lack the distro tools like makeinfo. It results in things like this: ./bootstrap: 255: makeinfo: not found ./bootstrap: Error: 'makeinfo' not found I tried the MAKEINFO=true tricks but they did not work. H

Segfault in Bash

Hi Everyone, I'm working on a script to find all shared objects in a directory. A filename should match the RE '*.so$'. I thought I would pipe it to grep: $ ./audit-libs.sh /home/jwalton/tmp/ok2delete/lib ./audit-libs.sh: line 17: 22929 Segmentation fault (core dumped) $(echo "$file" | grep

Use of `mktemp' is dangerous, better use `mkstemp'...

Hi Everyone, I'm building Bash 5.1 from sources. This may be of interest: /usr/bin/ld: ./lib/sh/libsh.a(tmpfile.o): in function `sh_mktmpname': /home/jwalton/Build-Scripts/bash-5.1/lib/sh/tmpfile.c:160: warning: the use of `mktemp' is dangerous, better use `mkstemp' or `mkdtemp' Jeff

Bash 5.1 and Ncurses

Hi Everyone, I configured Bash 5.1 with prefix=/usr/local, --with-curses and --enable-multibyte. The link failed with undefined references, like tputs. I have the wide char Ncurses built and installed in /usr/local. I found I needed to add -ltinfow to LIBS and LDLIBS for the build to succeed. I'm

Hi Everyone, I'm testing on Ubuntu 18.05 x86_64 fully patched. It looks like the man2html recipe is not using LDFLAGS: /usr/bin/cc -DHAVE_CONFIG_H -DSHELL -I/home/jwalton/Build-Scripts/bash-5.1 -I.. -I/home/jwalton/ok2delete-asan/include -DNDEBUG -DTEST_ASAN=1 -g2 -O2 -fsanitize=address -fno-omi

Crash in malloc.c : internal_malloc under Asan

Hi Everyone, I'm trying to use an Asan-instrumented version of Bash for my shell. Bash is dying in startup code. The source file is malloc.c (missing from Bash sources at https://git.savannah.gnu.org/cgit/bash.git/tree/), and the function is internal_malloc. The Asan folks have a suspicion of mal
