Install script seems to need bash

• [] Did you use the latest version of GEF from dev branch?
• [n/a ] Is your bug specific to GEF (not GDB)? - Try to reproduce it running gdb -nx
• Did you read the documentation first?
• Did you check issues (including
  the closed ones) - and the PR?

Step 1: Describe your environment

• Operating System / Distribution: Ubuntu 20.04
• Architecture: x86 64bit
• GEF version:

GEF: (Standalone)
SHA1(/home/vanderaa/.gef-e95b072f5684857ffd3d3c95c3369f83cdba0dee.py): 743f638904c44c815ed815b7530c0d07069e775e
GDB: 9.2
GDB-Python: 3.8

Step 2: Describe your problem

Steps to reproduce

Install command fails with sh:

$ wget -q -O- https://github.com/hugsy/gef/raw/master/scripts/gef.sh | sh
sh: 6: test: unexpected operator

Works with bash:

$ wget -q -O- https://github.com/hugsy/gef/raw/master/scripts/gef.sh | bash

/bin/sh is dash on Ubuntu:

$ dpkg -S /bin/sh
diversion by dash from: /bin/sh
diversion by dash to: /bin/sh.distrib
dash: /bin/sh
$ dpkg -s dash | grep Version
Version: 0.5.10.2-6

When adding set -x around line 6:

$ sh gef.sh
+ test  == dev
gef.sh: 7: test: unexpected operator
+ set +x

Where are you seeing instructions that say to use sh?

# via the install script
## using curl
$ bash -c "$(curl -fsSL http:https://gef.blah.cat/sh)"

## using wget
$ bash -c "$(wget http:https://gef.blah.cat/sh -O -)"

# or manually
$ wget -O ~/.gdbinit-gef.py -q http:https://gef.blah.cat/py
$ echo source ~/.gdbinit-gef.py >> ~/.gdbinit

# or alternatively from inside gdb directly
$ gdb -q
(gdb) pi import urllib.request as u, tempfile as t; g=t.NamedTemporaryFile(suffix='-gef.py'); open(g.name, 'wb+').write(u.urlopen('https://tinyurl.com/gef-master').read()); gdb.execute('source %s' % g.name)
