| 4 | pySim-shell is an interactive command line shell for all kind of interactions with SIM cards. |
| 5 | |
| 6 | The interactive shell provides command for |
| 7 | |
| 8 | * navigating the on-card filesystem hierarchy |
| 9 | * authenticating with PINs such as ADM1 |
| 10 | * CHV/PIN management (VERIFY, ENABLE, DISABLE, UNBLOCK) |
| 11 | * decoding of SELECT response (file control parameters) |
| 12 | * reading and writing of files and records in raw, hex-encoded binary format |
| 13 | * for some files where related support has been developed: |
| 14 | |
| 15 | * decoded reading (display file data in JSON format) |
| 16 | * decoded writing (encode from JSON to binary format, then write) |
| 17 | |
| 18 | By means of using the python ``cmd2`` module, various useful features improve usability: |
| 19 | |
| 20 | * history of commands (persistent across restarts) |
| 21 | * output re-direction to files on your computer |
| 22 | * output piping through external tools like 'grep' |
| 23 | * tab completion of commands and SELECT-able files/directories |
| 24 | * interactive help for all commands |

| 34 | ISO7816 commands |
| 35 | ---------------- |
| 36 | |
| 37 | This category of commands relates to commands that originate in the ISO 7861-4 specifications, |
| 38 | most of them have a 1:1 resemblance in the specification. |
| 39 | |
| 40 | select |
| 41 | ~~~~~~ |
| 42 | |
| 43 | The ``select`` command is used to select a file, either by its FID, AID or by its symbolic name. |
| 44 | |
| 45 | Try ``select`` with tab-completion to get a list of all current selectable items: |
| 46 | |
| 47 | :: |
| 48 | |
| 49 | pySIM-shell (MF)> select |
| 50 | .. 2fe2 a0000000871004 EF.ARR MF |
| 51 | 2f00 3f00 ADF.ISIM EF.DIR |
| 52 | 2f05 7f10 ADF.USIM EF.ICCID |
| 53 | 2f06 7f20 DF.GSM EF.PL |
| 54 | 2f08 a0000000871002 DF.TELECOM EF.UMPC |
| 55 | |
| 56 | Use ``select`` with a specific FID or name to select the new file. |
| 57 | |
| 58 | This will |
| 59 | |
| 60 | * output the [JSON decoded, if possible] select response |
| 61 | * change the prompt to the newly selected file |
| 62 | * enable any commands specific to the newly-selected file |
| 63 | |
| 64 | :: |
| 65 | |
| 66 | pySIM-shell (MF)> select ADF.USIM |

| 125 | pySim commands |
| 126 | -------------- |
| 127 | |
| 128 | Commands in this category are pySim specific; they do not have a 1:1 correspondence to ISO 7816 |
| 129 | or 3GPP commands. Mostly they will operate either only on local (in-memory) state, or execute |
| 130 | a complex sequence of card-commands. |

| 231 | cmd2 settable parameters |
| 232 | ------------------------ |
| 233 | |
| 234 | ``cmd2`` has the concept of *settable parameters* which act a bit like environment variables in an OS-level |
| 235 | shell: They can be read and set, and they will influence the behavior somehow. |
| 236 | |
| 237 | conserve_write |
| 238 | ~~~~~~~~~~~~~~ |
| 239 | |
| 240 | If enabled, pySim will (when asked to write to a card) always first read the respective file/record and |
| 241 | verify if the to-be-written value differs from the current on-card value. If not, the write will be skipped. |
| 242 | Writes will only be performed if the new value is different from the current on-card value. |
| 243 | |
| 244 | If disabled, pySim will always write irrespective of the current/new value. |

| 248 | |
| 249 | This parameter determines if generated JSON output should (by default) be pretty-printed (multi-line |
| 250 | output with indent level of 4 spaces) or not. |
| 251 | |
| 252 | The default value of this parameter is 'true'. |
