cut a string in a textfile line per line

i need to cut the string in a textfile but each line has a specific way of cutting it (different lengths)

i have a for loop that gets the string line per line, then each line has to be compared:

Code:
for x in `cat tmp2.txt`; do
       if[ "BAC" == _____  ]; then
               echo 'BAC'
       elif[ "sdf_ada" == _____]
         etcetc
       fi
done

sample tmp2.txt file that needs to be trim to specific length :
BAC0904102604 -> BAC
AFR0904102604 -> AFR
HHF0904102604 -> HHF
UI100904102907 ->UI10
sdf_ada_9541-9543.1 -> sdf_ada
_fsf13145533 ->fsf

note: the file is in random order.

NAME
xcutsel - interchange between cut buffer and selection SYNOPSIS
xcutsel [-toolkitoption...] [-selection selection] [-cutbuffer number] OPTIONS
xcutsel accepts all of the standard X Toolkit command line options as well as the following: This option specifies the name of the selec- tion to use. The default is PRIMARY. The only supported abbreviations for this option are "-select", "-sel" and "-s", as the standard toolkit option "-selectionTimeout" has a similar name. This option specifies the cut buffer to use. The default is cut buffer 0. DESCRIPTION
The xcutsel program is used to copy the current selection into a cut buffer and to make a selection that contains the current contents of the cut buffer. It acts as a bridge between applications that do not support selections and those that do. By default, xcutsel will use the selection named PRIMARY and the cut buffer CUT_BUFFER0. Either or both of these can be overridden by com- mand line arguments or by resources. An xcutsel window has the following buttons: When this button is pressed, xcutsel exits. Any selections held by xcutsel are automatically released. When this button is pressed, xcutsel copies the current selection into the cut buffer. When this button is pressed, xcutsel converts the current contents of the cut buffer into the selection. The button labels reflect the selection and cutbuffer selected by command line options or through the resource database. When the "copy 0 to PRIMARY" button is activated, the button will remain inverted as long as xcutsel remains the owner of the selection. This serves to remind you which client owns the current selection. Note that the value of the selection remains constant; if the cutbuffer is changed, you must again activate the copy button to retrieve the new value when desired. X DEFAULTS
This program accepts all of the standard X Toolkit resource names and classes as well as: This resource specifies the name of the selection to use. The default is PRIMARY. This resource specifies the number of the cut buffer to use. The default is 0. WIDGET NAMES
The following instance names may be used when user configuration of the labels in them is desired: This is the "copy SELECTION to BUFFER" button. This is the "copy BUFFER to SELECTION" button. This is the "quit" button. BUGS
There is no way to change the name of the selection or the number of the cut buffer while the program is running. SEE ALSO
