# 2003-08-02 first version |
| 9 |
# 2003-08-03 using mktemp to create temp files, auto-install iselect |
| 10 |
# 2003-08-04 catch signals so temp files are not left behind, added |
| 11 |
# enter new search at end of results, autoconfig |
| 12 |
# 2003-08-06 changed delimiter to \s/ to prevent conflict with e-mails |
| 13 |
# 2003-08-15 automatically run apt-get update if there is no package list |
| 14 |
# (e.g. changing apt/sources.list without update), cut lines |
| 15 |
# to 80 chars before sending to iselect (bug workaround) |
| 16 |
# 2003-08-31 changed delimiters to {}, q on detail page brings back list of |
| 17 |
# results, highlighted search word(s) in package details |
| 18 |
# 2003-09-01 changed script to work with any POSIX complient shell, and not |
| 19 |
# only bash (thanks to Ulrich Doehner for bug report and |
| 20 |
# suggestions), added support to use su if sudo is not |
| 21 |
# installed, fixed search with more than one word (thanks |
| 22 |
# to Tobias Gruetzmacher who reported this bug) |
| 23 |
# 2003-09-04 moved do_sudo before first call (fixes bug when trying to |
| 24 |
# install iselect) |
| 25 |
# 2003-10-09 allow multi-selection of packages to view details |
| 26 |
# 2003-11-13 fix for RedHat 9.0 mktemp bug suggested by Dobes Vandermeer |
| 27 |
# 2004-07-27 allow multi-selection of packages to install |
| 28 |
# |
| 29 |
# I know it's ugly, but it's still faster than aptitude :-) |
| 30 |
# |
| 31 |
# It will automatically use sudo if installed or require user to enter root |
| 32 |
# password when needed. It will also install iselect deb package |
| 33 |
# if it's not already there. |
| 34 |
# |
| 35 |
# WARNING: due to iselect limitation, maximum number of results is |
| 36 |
# 1020 and maximum length of all results is 1048576 bytes |
