SpaceFM 0.7.2 is available.
New Bash Function
The function spacefm uses to run bash via various su programs and terminals has been redesigned and rewritten. This function had become a bit overgrown due to the inconsistency among su programs and terminals. The new version is much cleaner and should provide for more flexibility for future uses. Although the changes should be transparent to most users, you may want to note the following changes:
- spacefm now uses a single temporary script to run bash commands and scripts, rather than separate exec and source scripts
- a new intermediary permanent script ‘spacefm-auth’ is now installed to /usr/bin (or /usr/local/bin). This script simplifies the commands passed on the command line to su programs, and is used to authenticate temporary scripts run as another user (such as root) using sha256sum.
- spacefm’s temporary directory (/tmp by default) can now be mounted with the ‘noexec’ option if desired
- spacefm now supports the new ktsuss2, with some reservations (see below)
If you do notice a command/su/terminal combination that no longer works, please let me know so I can accommodate it. I have tested the new function but it is impossible to test every possible use due to the number of combinations – that’s where your feedback comes in.
The developer of ktsuss has released version 2 which addresses two security problems present in ktsuss 1.4 and earlier. However, ktsuss2 has also introduced some bugs which limit its ability to be used in all circumstances. I have discussed these with David Cortarello and he said he would look at the issues.
The primary bugs which affects use of ktsuss2 in spacefm 0.7.2 is that ktsuss2 does not return the exit status of the command being run, and it discards the stderr output of the command. This means that commands run in spacefm with ktsuss2 will present no error dialog or output if the command fails – you won’t know it failed. So I cannot recommend use of ktsuss2 at this time.
Below are some of my bug reports on ktsuss2. Except for the error issues above, the rest of these issues should not affect spacefm 0.7.2 and later, but do affect earlier versions.
The icon sizes 20×20 have been replaced with 22×22 to prevent unnecessary scaling which caused blurring of some icons.
Also, the close buttons on tabs now use a smaller icon.
Also, the icons in the Devices and Bookmarks lists, and in the directory tree side pane now obey the small icon size set in preferences. Some custom icons you have specified may look different or not work in version 0.7.2 due to changes in the way they are loaded.
MBR & FSArchiver
spacefm can now create MBR and FSArchiver backups of mounted volumes. For FSArchiver, the volume generally has to be mounted read-only, or you have to specify ––allow-rw-mounted
The SpaceFM User’s Manual has been updated to reflect changes and minor corrections.

Although most users across many distros are reporting high stability using spacefm, some users have commented about crashes but have not filed bug reports. In case you think the developer sees these too, I do not – spacefm never crashes for me, and if it does, I fix it. The only way other crashes will be fixed is if they are reported with enough detail on what triggers them. Preferably, also install gdb, build spacefm with the appropriate flags, and provide a backtrace. Otherwise fixing such bugs is like finding a needle in a haystack.
As of version 0.7.2, the only reproducible and sufficiently detailed crash is this one, which is caused by a bug in libgdk-pixbuf which they have done nothing to correct thus far. However, that crash only affects one known particular icon file, although there could be others.
Although 100% stability is simply not possible in the environment spacefm is run in, the way it will achieve its highest stability is for the users experiencing such problems to take the time to make detailed reports. This goes for more minor bugs too. spacefm has many flexible functions which makes it hard to test completely. If you find a minor bug, please report it. Your testing and feedback is appreciated and helps to improve the software.
More distributions have added spacefm to their repositories or have test packages available. These now include:
- Gentoo’s portage tree includes spacefm
- Sabayon includes spacefm in its repositories
- Arch Linux’s AUR includes spacefm
- PCLinuxOS has spacefm test packages available (see forum)
- VectorLinux has spacefm test packages available
spacefm has been getting some good press, which is helpful for letting new users know about it. Linux Format magazine will have an article about spacefm in their April 2012 print issue, in the LXFHotPicks section. I received a complimentary copy and they gave a very positive review. WEB UPD8 also has an online review.
